I power washed my CJ 2 weeks ago, trying to pinpoint a coolant leak, and nothing has been the same since.
The Jeep starts no problem and runs great when in driving, but as soon as I let off the gas it dies. It always starts back up after it dies. I have looked for vacuum leaks, and tracked down misplaced vac hoses and reconnected them back as close to the original hose diagram as possible. The PO had made several changes and rerouted wiring and hoses all over the place. I have sprayed B12 on the distributor and cleaned and dried both the distributor and cap. I have changed the spark plugs and wires. I have looked and I get two steady streams of fuel when the engine is off, until the bowl is full. I have adjusted the idle screw and nothing has fixed my issue.
Today I finally got it to start and idle for almost 15 minutes. Once it warmed up and was running ok I opened the throttle and as it came back down to idle, it began to run rough, and eventually tried to stall, unless I forced fuel. When I opened the throttle while it was running, I didn't see any fuel coming going into the carb, and instead got a sucking sound. I also noticed that the further the valve at the top of the carb opened up the rougher it idled, until eventually the valve stood strait up and it finally died.

I have only owned the Jeep for 6 weeks or so and it was running pretty well until I power washed it. It hasn't been on the road since. It is an '84 CJ7 with a 4.2L strait 6. I can add more pictures and/or details if needed. I am a novice mechanic at best, but I do have some decent help when needed. I bought this to help me learn and enjoy with while I worked on. Any help is appreciated.

Regards,
GR

SOUNDS LIKE YOU NEED SOME TUNING

6 WEEKS, HUH?

WHAT HAVE YOU DONE TO GET YOUR PREVENTATIVE MAINTENANCE UP TO DATE AND ALL CAUGHT UP?

WHAT PART OF THE COUNTRY ARE YOU IN?

DO YOU HAVE A TACH/ DWELL METER?

A PLAIN JANE TIMING LIGHT (NO NEED TO HAVE AN ADJUSTABLE ONE)

SET OF SAE WRENCHES? SCREWDRIVERS?

BONUS- A VACUUM GAUGE?

YOU DID WIPE OUT THE INSIDE OF THE DISTRIBUTOR CAP?

HOW FAR YOU GONNA GO WITH GETTING HIM RIGHT?

BUDGET?

WHAT IS NOT ORIGINAL ON THIS? CARB? IGNITION? ETC?

I CAN TALK YOU THRU NEARLY ALL OF THIS ALONG WITH PICS

I CATCH UP WITH IT ALL/ INCLUDING FLUID CHANGES-I TRUST NO ONE ELSES CLAIMS OF "TAKING CARE" OF THEIR STUFF-WIFE AND OTHERS SAY I'M A-NAL!

I'VE OWNED NOTHING BUT CJs SINCE I WAS ALLOWED ON THE ASPHALT IN 1981-I KNOW HOW TO DESTROY 'EM AS WELL AS (NOW A DAYS) KEEP 'EM GOING WELL. I'VE OBTAINED AND REBUILT THESE 2 IN MY PICS BACK IN 1991, BOTH ARE DAILY DRIVERS

Medic,
thanks for your reply. I have read through several of your other posts this afternoon, and I appreciate your willingness to help.
I have also followed some of your basic advice from other posts (tighten the bolts screws on the carb) I thought I had it starting to get better, and found that the op gasket was very warn. Then I did something, don't really know what, but now the valve on the top of the carb is stuck in full open, and I can only close it manually. It will however begin to open on its own, as the throttle is engaged. 1 step forward 2 steps back for me on this lately. I have added some pics as well to help you see what I have.

I will go through your questions below as I believe that is the easiest way not to leave anything out.

6 WEEKS, HUH? Yes I had my mechanic look at it and everything was mechanically sound. The 2 problems we knew of were an very small oil drip from the dipstick case, and a small coolant leak from behind the pump near the front of the block, that remains unidentified. I was power washing the engine to clean off the grime to help track down where the coolant leak was coming from, and then I made this mess.

WHAT HAVE YOU DONE TO GET YOUR PREVENTATIVE MAINTENANCE UP TO DATE AND ALL CAUGHT UP.
I have changed the spark plugs and wires, and the oil was changed 3 weeks before I got it (I had the receipt). Not sure when other fluids were last changed, but all inspected by my mechanic, and I was told all was good.
WHAT PART OF THE COUNTRY ARE YOU IN?
I live in the very dry and dusty West Texas

DO YOU HAVE A TACH/ DWELL METER?
No, but I will get them tomorrow if necessary
A PLAIN JANE TIMING LIGHT (NO NEED TO HAVE AN ADJUSTABLE ONE) Yes.

SET OF SAE WRENCHES? SCREWDRIVERS? Yes.

BONUS- A VACUUM GAUGE? No, but again if I need one I will get one.

YOU DID WIPE OUT THE INSIDE OF THE DISTRIBUTOR CAP?
Yes I believe I cleaned it quite well, and inspected for cracks. Worked on it this weekend, and my father in law and I both believe it to be working well.

HOW FAR YOU GONNA GO WITH GETTING HIM RIGHT?
I want the Jeep to run right, and I plan to keep it for some time. I bought it for a 2 reasons. 1) to enjoy with my kiddos on the weekends, run to the pool, or store or pick up my son from school without the top and doors.
2) to develop some mechanical aptitude, and learn how to do more that an oil change (Some jest there, but not as much as I would like).

BUDGET? I will spend what I need to, but I don't want to go crazy on something that is simply for sunny days when I am not working. I already have plans and the $ set aside for to slandbast it and have it painted this winter. I was about to order fuel/ temp and tach gages as mine don't work. Then I caused this problem. I know that is not an answer, but I hope it helps get to my line of thinking.

WHAT IS NOT ORIGINAL ON THIS? CARB? IGNITION? ETC?
I believe most of the Jeep is stock. I have an MSD Distributor, and Electronic ignition. Couldn't tell you how old they are, but they look relatively new. Also the fuel filter and pump look to have been replaced. As I mentioned the plugs and wires are also less than a week old. My father in law believes that the motor has been replaced because the AC unit is not hooked up, and the pulleys do not align with any of the other belt routing. If it has been replaced, it was with another 258 I6. The gaskets and seals have been replaced in some spots, as you can see gel coming out in some spots. There is wires all over this thing, and many have been cut and left to dangle, but the wiring that is intact seems to be relatively new as well.

I CAN TALK YOU THRU NEARLY ALL OF THIS ALONG WITH PICS
Thanks so much. For a newbie like me I need all the help and basic instructions and pictures I can get.

I CATCH UP WITH IT ALL/ INCLUDING FLUID CHANGES-I TRUST NO ONE ELSES CLAIMS OF "TAKING CARE" OF THEIR STUFF-WIFE AND OTHERS SAY I'M A-NAL!
I have been called that as well, and I think its a badge of honor.

Thanks Again, GR

YOUR PICS MAY BE "TOO BIG"

SINCE I'VE BEEN HERE THE SITE HAS CHANGED SEVERAL TIMES

I CAN NO LONGER USE MY REBEL T-3 WITHOUT RESIZING THE PICS

I CONTINUE TO USE MY KODAK EZ SHARE TO MAKE DECENT PICS THAT I DON'T HAVE TO MESS WITH

I'M STILL ONE W/ A DINOSAUR FLIP PHONE-I DO NOT PARTICIPATE IN "DRAMA BOOK" NOR DO I "TELETYPE" ON IT, AS IT IS EZier AND FASTER TO USE MY MOUTH AND EARS TO COMMUNICATE,THIS ALSO LETS ME HEAR INFLECTIONS IN A VOICE, THUS THE "COMMO MOOD" IS SET (LIKE KNOWING IF THE WIFE IS MAD AT ME!)

I HOPE YOU DO NOT MIND LINKING-I DO IT A LOT TO SAVE ME SOME TIME, IT GETS YOU INFO FASTER

ARE YOUR EMISSIONS TESTED IN YOUR AREA?

YOU SAY VACUUM LINES MAY HAVE BEEN CHANGED? IF THEY DON'T CHECK YOU, WE MAY BE ABLE TO ELIMINATE MANY, AND KEEP A FEW. IT ONLY TAKES A FEW TO MAKE IT RUN WELL

DWELL/ TACH MAY BE A DINOSAUR "CHEAP" PAWN SHOP ITEM!

THE VACUUM GAUGE CAN WAIT

1ST LINK-IT DOES NOT HAVE TO BE ICE OUTSIDE TO SET THE CHOKE. SEE "MY ANSWER" CONCERNING THE CHOKE ADJUSTMENT ON "APRIL 13, 2013"

http://www.2carpros.com/questions/1981-jeep-cj7-problem-cj-7-sat-years-started-died-after-about-mile/page/2

REMEMBER, THE THROTTLE LEVER NEEDS TO BE OPEN TO UNLOCK THE CHOKE STUFF

LAY YOUR HOOD BACK ON THE WINDSHIELD FRAME/ REMOVE THE AIR CLEANER- SEND ME GOOD PICS OF DRIVER, PASSENGER, OVERHEAD OF THE ENGINE, ESPECIALLY THE VACUUM LINES (FAR ENOUGH OUT TO IDENTIFY THEM)

SEND ONE OF YOU POINTING AT YOUR SUSPECTED COOLANT LEAK TOO

YOUR TURN,

Thanks for the info on the Pics.
I don t mind a matter of fact I have been following on of your older posts on rearranging the vac lines. http://www.2carpros.com/forum/1985-jeep-cj7-stalls-when-hot-vt452051.html
I do not live in an area with emissions testing. Also I think I am exempt in Texas because the CJ is over 30 years old, but I could have dreamed that. Either way I am good.
I actually went to by replacement hoses today but they were out of 1/4" fuel line, and I didn t have time for the kid to go to the back and look around for it. I will try to start that project on Friday, unless you tell me otherwise.

In fact since my pictures didn t work I am going to try something new for me. A link for you to my pictures. Hopefully this works. I am not that tech savvy either, so we will see. http://s1284.photobucket.com/user/grasor1/embed/slideshow/
I took these in the dark tonight, so they didn t turn out as well as I hoed. I can add more during the daylight if these don t show you what you are looking for.

As far as the routing of the vac lines I will try to explain the best I can.
Distributor to front port on carb.
drivers side of carb to Vac canister
Back of Carb (bellow stepper motor) to "golden looking thing that moves the choke arms"
Manifold valve is looped together.
Bell thing below the carb (ERG I think) capped
PCV to passenger side of carb
2 units with 2 vac ports each on top of firewall Nothing attached
Coffee can on passenger side near firewall Nothing attached.
Probably missed one or 2, but hopefully not.

I will start looking for the Dwell/Tac right away, will let you know once I get one.

Not sure if I did a good enough job getting a pic of the coolant leak, but in short it is a very small pool of coolant on the driver s side of the block, near the first cylinder. I don t have any dripping on the ground, and when it was driving ok, I never saw the leak, only when it is sitting and idling. First noticed it when the mechanic checked it out. He thought it could be a head or valve cover gasket that was old. I have since noticed it 2 other times when I was working under the hood, and had the engine running. My buddy said freeze plugs, I thought water pump. Who knows. I don t seem to be losing fluid out of my overflow tank, so hopefully it s not a major issue, but I wanted to repair it before it became one.

Thanks, GR

I TRY TO MAKE IT INTERESTING AND EVEN FUNNY- HIGHER UP HAS TAKEN MY ORIGINAL MEMBERSHIP AWAY FROM ME, LET ME HAVE A NEW ONE, HOWEVER I DON'T SEEM TO HAVE ACCESS TO AN AVATAR AND OTHER STUFF AS BEFORE....SOMEHOW I HAVE PIZZED 'EM OFF

I REALLY HATE THE "SILHOUETTE" NOGGIN' THAT SHOWS UP NOW

IS MY PAST/ PRESENT CRAP AIDING YOU?

BACK OFF SOME WITH THE LEAK PICS--TOO CLOSE!

MAY BE THAT THE THERMOSTAT SLIPPED SLIGHTLY OUT OF THE BOTTOM OF THE HOUSING DURING INSTALL! HARD TO TELL- USE MAMA'S COMPACT (MIRROR) TO LOOK UNDER THERE!

GONNA INSTALL A NEW ONE? SEE THIS LINK 1ST

Thanks Medic,
I m not sure what the apology was for, but whatever it was, you are ok in my book. You have taken your time to help me solve this issue including labeling my pics so I can easily understand what you are telling me. I appreciate all your posts, and I do find you informational and appreciate your willingness to help complete strangers fix their CJ s. Looks like you have been doing this for quite some time, and it s too bad you had to get a second account name, and no more avatar.
I am planning on getting to work on replacing hoses tomorrow, and I will pick up a filter for the carb bowl vent as well.
I will also try to get you some better pics of the leak, in the morning, when I have better lighting.
Pics are great and I can read them great. One question I have is the PCV on the rear of the block that you told me to gut, I thought that was some time of aftermarket air intake device. Is this not the case? It is freestanding, and not attached to any hoses at all. Should I just scrap it and plug the port? Would their be a reason the PO would have added this? I will add pics of this as well.

I do have power breaks.

Talk to you soon.

YOU GOTTA KEEP THE PWR BRAKES VACUUM LINE-IT SHOULD BE ON A "BIG" VACUUM PORT

THE ONLY OTHERS YOU HAVE TO HAVE ARE THE

DISTRIBUTOR VACUUM ADVANCE (MINE WORKS BEST ON MANIFOLD VACUUM-ON OTHERS,FOLKS-ES, PORTED VACUUM MAY WORK BEST)

THE PCV VAC LINE TO A "BIG" MANIFOLD VACUUM PORT

IF YOUR A/C WORKS, IT MAY NEED VACUUM TOO

I HAVE AN "ON DASH VACUUM GAUGE" IT REQUIRES MANIFOLD VACUUM

EVERYBODY ELSE IS USELESS!

THIS INCLUDES ALL OF THAT TANGLED MESS=EVEN THE EGR IS NOT NEEDED (WHEN YOU INSTALL HEADERS, THE EGR IS ABANDONED! SO IT IS UNNECESSARY!)

CAP OFF ALL UNUSED VACUUM PORTS. I LIKE THE VINYL CAPS, THEY DO NOT ROT AWAY LIKE THE RUBBER ONES

WHEN ALL OF THIS CRAP WAS NEWER, AND WORKED IT DID MOVE THE STEPPER ON THE CARB, AND SUPPOSEDLY WAS WONDERFUL

NOW IT AIN'T WORKING AND THE CARB IS LIKE ANY OTHER BBD-YOUR CARB IS EXPENSIVE TO REBUILD-AND DON'T WORK AS INTENDED

I CAN LINK YOU TO YET ANOTHER POST WHERE WE MAKE YOUR ENGINE AND CARB BASICALLY BACK INTO A 1979! EZ AND CHEAP! IF YOU DECIDE TO DO A NEW PLAIN JANE BBD NO BELLS AND WHISTLES-I PROMISE-IT WILL FIT!

SEE APRIL 25, 2014 AND THE EBAY LINK IN IT

http://www.2carpros.com/questions/1986-jeep-cj7-cannot-start

BACK TO THE PCV

MR. PCV SUCKS OUT ALL OF THE HARMFUL GASES AND WATER IN THE ENGINE'S AIR SPACES

IT SUCKS 'EM INTO THE INTAKE MANIFOLD TO BE BURNED

AS IT SUCKS OUT THE AIR, IT MUST BE REPLENISHED WITH FRESH AIR (VALVE COVER REAR HOLE)

THE AIR MUST BE FREE FLOWING INTO THE VALVE COVER (WHETHER IT'S YOUR FILTER OR MY AIR CLEANER)

PULL OUT YOUR FILTER AND IT'S GOODIES-NOW PRETEND YOU ARE THE VALVE COVER NEEDING FRESH AIR-ACTUALLY SUCK ON THE BOTTOM OF THAT "IMPOSTER ELBOW PCV"-IF IT "CHECKS"-YOU ARE NOT GETTING "MAKE UP AIR" INTO THE ENGINE

SIMPLE FIX-GRIND OFF THE BOTTOM AND REMOVE THE SPRING AND GUTS-NOW YOU HAVE AN "ELBOW" THAT LOOKS LIKE A PCV!

YEAH-THEY DID THIS CAUSE IT FIT WELL AND HAD NO CLUE IT WOULD STARVE TH CARB OF AIR, ESPECIALLY MORE AT IDLE SPEED!

THIS MAY BE ONE OF YOUR PROBLEMS

HOW ARE WE DOIN'?

UNDERSTAND THE STUFF I'M SHOVELIN'?

I'M SO GLAD YOU KEEP RESPONDING, I REALLY LIKE TO KNOW I'M STILL NEEDED. CJs ARE FEW AND FAR BETWEEN ON HERE

OTHER CRAP TO SEE MIGHT BE FOUND ON YAHOO / GOOGLE / ETC BY TYPING IN "2CARPROS" AND "CJ MEDEVAC" ON THE SEARCH BAR-THEN HIT "IMAGES"

IT'S LATE-I'LL LOOK AT YOUR PICS TOMORROW

KEEP IT UP-LET ME KNOW WHAT IS NEXT

OH YEAH!

MORE ON THE PCV AND CARB

JUST THROWING STUPID NUMBERS/ AS I AM NO SCIENTIST/ BUT I DO KNOW THE "BIG PICTURE"

LET'S SAY THE CARB IN ALL PERFECTION IS WORKING 100% EFFICIENT AT IDLE

IT'S CRACKED OPEN AND CONSUMING 5 CFMs OF OUTSIDE AIR

IT'S ALSO CONSUMING 1 CFM OF AIR FROM THE PCV (RE-ROUTED, NOW "DIRTY AIR"), THE "PCV" IS MATCHED TO THIS CARB, AS
IT'S DESIGN ALLOWS THE CORRECT AMOUNT OF AIR THRU

THERE ARE HUNDREDS OF PCVs OUT THERE-USE THE RIGHT ONE!

THE INTERNAL PASSAGES AND JETS OF THE CARB ARE "BUILT" FOR THIS "6" CFMs OF AIR

CHANGE THE VALUES AND IT WON'T ADJUST RIGHT, NOR BE AT 100%-LIKE RESTRICTING THE FLOW AS YOUR IMPOSTER PCV ELBOW IS DOING!

CASE IN POINT

IF YOU DO GO WITH A 1979 TYPE CARB INSTEAD OF THE STEPPER TYPE-YOU WILL NEED TO USE A 1979 PCV TO KEEP THINGS SORTA CALIBRATED

YOU CAN VERIFY THIS BY LOOKING UP PICS/ PART NUMBERS AT ONLINE AUTO PARTS STORES OF DIFFERENT YEARS OF JEEPS OR OTHER VEHICLES

BED TIME,

Thanks Medic,
I was adding some additional info and right as I was finishing I lost everything. Oh well once I reopened the page I saw your posts.
Yes I am picking up what you are putting down, no problem.
I have a couple of questions when you look at my pics tomorrow, and I have attached 2 more here, hopefully they fit.
1) I have completed the vacuum hose replacement, per your earlier post linked above. I think it helped, but I had to run as soon as I finished so I dint get to play with it much to really tell. I will add pics tomorrow of the reroute. Breaks are connected to the big port on drivers side of carb. I will check out the filter on the rear PCV and get it fixed.
2) I have changed the real PCV hose, as mine was pretty nicked up. I have added the pic below. 2 problems:
a. They didn t have 3/8 fuel hose so I had to buy radiator hose. Will this work ok, or do I need to replace?
B. The PCV from the front of the block runs to a T near the back of the carb where it hits some electrical device, then it T s again and heads to the carb and to the vac canister. Do you know what this devise is, and should all of this be removed and go straight from PCV to the Carb? Pic attached and labeled. Hope it helps clear up what I am saying.
3) I have added a pic of the idle screw. I only have one. After reading through the link from yesterday, I noticed I do not have a curb idle screw. Is this causing me issues?
4) Realizing that I don t really know what I am doing. I don t see the pins moving in the back of the carb, not matter what adjustments I make. I am wondering if I messed up the stepper motor, and that is the root of the idle problem. You mentioned taking the carb to the 79 version. I will read through that post and get back to you. I have been quite frustrated with this issue, and I have been contemplating just replacing the carb. Do you think this is necessary/useful, or is that an overreaction at this point?
Again I appreciate all your help. Will look forward to more of your input soon

Thanks Medic,
I will scrap all the devices, and run the hoses straight through. I have added pics of what I have done so far. Hopefully you can read all my labels, and see the pics clearly enough to tell what is what.

1 question: I thought you put the filter on the end of the hose at carb vent? Do you have more than one 3/8" fuel filter, or did I misunderstand?

I think the stepper either was broken before or is now after I messed with it today, pics attached.
I am thinking about going with a Motorcraft 2100 carb. I can buy a rebuilt carb, pre tuned for my CJ and the adaptor kit for less than $300. I know I can buy a new Carter slightly cheaper, but from everything I have read, the MC is a better carb. I can also pull one from a salvage yard and rebuilt kit on the MC for about $150 all in. Any advice there, had any dealings with the MC2100?
Thanks for all your help.

IF YOU WILL LOOK BACK AT THE PIC OF THE BOWL VENT ( I'LL POST IT BELOW) MY FILTER (DUST/ BUG CONTROLLER WAS DANGLIN' ON THE LOWER LINE, JUST DANGLED BELOW THE CARB--SORTA LOOK HOW I PASTED THE FILTER IN THE PIC

ALL RIGHTY THEN

AS FAR AS CARBS GO

I'VE HAD A "WO" AND NOW A "SOLEX" IN "WILLY

IN MY OTHER 6 CJs, I'VE HAD A "CARTER YF" (1 BBL), "CARTER BBDs (SEVERAL), A "MOTORCRAFT" (ON MY 1st, A 304), ON THE PRESENT ONE, STARTED WITH A "BBD", TRIED A "WEBER DGEV", AND NOW I'M REALLY HAPPY WITH THE "HOLLEY 390" AND 4 BBL OFFENHAUSER INTAKE.

MY QUEST FOREVER HAS BEEN MAX MPGs (EVEN IF I SPENT A FORTUNE GETTING THERE!)

I'VE TRIED MIGHT NEAR EVERY GIMMICK, RANGING FROM OPPOSING MAGNETS ON THE FUEL LINE, TO THE "TORNADO" ATOP THE CARB AND SO MANY MORE.

I MAY NOT HAVE GIVEN THE WEBER A FAIR SHAKE, AS I WAS TRIAL AND ERRORing, THE JETS AND OTHER GOODIES THAT IT HAD (LIKE EMULSION TUBES, ETC.) I THINK I WAS TOO EAGER, AND HAVE SINCE LEARNED HOW TO "READ" MY FUEL MIXTURE USING AN O2 SENSOR

*******YOU STILL GOT AN O2 IN YOUR EXHAUST MANIFOLD?******

I CHOSE THE WEBER FOR 2 REASONS

1) PROMISE OF 20% MORE MPGs (I NEVER PASSED THE BBDs MPGS WITH IT)

2) PARTS WERE EZ TO ACCESS AND CHANGE, SUCH AS THE JETS-I DID HAVE TO ORDER THEM

AS FOR THE HOLLEY-I HAVE NEARLY $800 IN THE CARB AND INTAKE, YEP, I'M HARDHEADED!

HOWEVER, THE ONLY REASON I "AFFORDED IT" WAS I WON ENOUGH ON A LOTTERY TICKET TO COVER THE "SPUR OF THE MOMENT, COMPULSIVE PURCHASE"!

IT IS SO EZ TO "JET"/ MESS WITH THE FLOATS/ ALL OF MY PARTS ARE USUALLY "LOCAL"

I USUALLY GET 18 MPG OR SO WHEN I PAY ATTENTION TO MY DRIVING (I HAVE A VACUUM GAUGE ON MY DASH) THE COOL THING IS, I HAVE POWER WHEN I GET ON IT (WHICH I SELDOM NEED TO DO-I'M AN OLD 50 YEAR OLD FART NOW!)

HAD I NOT BEEN ABLE TO BUY THE HOLLEY AND INTAKE, MY PLAN WAS TO REVERT BACK TO MY 1979 BBD, I WAS NO LONGER FRIENDS WITH THE WEBER. I STILL HAVE MY OLD INTAKE AND CARB, JUST IN CASE!

OTHER JEEP PEOPLE THAT I ASSIST HAVE HAD VARIOUS CARBS ON THEIR 258s. MOST ARE A HASSLE TO CHANGE THE JETS OR MAKE ADJUSTMENTS

ONE PAL OF MINE HAS MODIFIED HIS DISTRIBUTOR, AS TO HAVE THE TOWERS FURTHER OUT FROM CENTER

HIS "REASONING" OR WHAT OTHERS "CRAMMED IN HIS HEAD WAS THAT THE OEM SET-UP WOULD "CROSSFIRE" AT HIGHER RPMs, AS THE "POSTS" WERE CLOSER TO EACH OTHER

BAH-HUMBUG!

ABOUT 100 MPH IS AS FAST AS I HAVE EVER DROVE MINE (ONCE OR TWICE, BACK WHEN I WAS BULLETPROOF!) 75 MPH IS AS FAST AS I WANNA GO THESE DAYS!

YOU KNOW, I NEVER EXPERIENCED "CROSSFIRE", OR IF I DID, I DID NOT KNOW IT?

DOING "WILD MODs" LIKE THAT REALLY MESS YOU UP WHEN IT'S TIME TO REPLACE "THAT PART" AT A PARTS STORE-OR EVEN WORSE, HAVING SOMEONE PICK IT UP FOR YOU WHEN YOU ARE ON THE SIDE OF THE ROAD

I'M GOING WITH THE THERMOSTAT HOUSING MAY BE LEAKING-MAYBE THE THERMOSTAT SLIPPED DOWN WHEN IT WAS BEING INSTALLED, NOW IT MAY BE PINCHED AT THE BOTTOM (DID THE MIRROR HELP?)

THERE IS THE POSSIBILITY OF A SEEPING HEAD GASKET OR A CRACK IN THE HEAD, BUT I REALLY DOUBT IT, MY MONEY'S ON THE THERMOSTAT HOUSING/ THERMOSTAT GASKET/ THE "SLIPPED" THERMOSTAT

THOSE VACUUM PORTS ON THE INTAKE (THE PLASTIC ONES) ARE VACUUM SWITCHES, THEY WORKED WHEN THE INTAKE (RADIATOR JUICE) GOT HOT- THERE AGAIN THEY ARE "JUNK" NO NEED TO CAP 'EM OFF, AS THEY ARE DEAD WITH NO HOSES CONNECTED. IF YOU WANT TO "SLICK THINGS UP", 3/8 INCH AND OR 1/2 INCH PIPE THREAD (NPT) PLUGS (STEEL OR BRASS) CAN TAKE THEIR PLACE

WHERE DO YOU STAND NOW? ARE YOU GETTING THINGS BETTER?

I'LL KEEP ON RESPONDING, AS LONG AS YOU DO!

YOUR LAST PICS WERE GREAT, SEND MORE AS YOU PROGRESS

Thanks for all the carb input. Things are not getting much better, as I havent realy had time to get out and work on it since Saturday morning. But I feel good that I have pinpointed my issue, as the carb. I can get her to idle beautifually as long as I hold the choke slightly closed. I thought about adjusting the choke, but then I figured even if I adjust it, once the engine warmed I would have the same issue that I don now. Now I just need to decide to bebuild the carter or put the MC2100 on it.

I wasn't able to tell if the thermostat or gasket has slipped, but I should have an extra hand to help in the next few days, and I am hoping to get a better look at it.
I will kepp you updated on my progress, and seend you pics as I move ahead.
Thanks,
GR

THIS MAY (OR MAY NOT HELP)

HAVE TO CHOKE?

SOMETIMES MEANS

NOT ENOUGH GAS

OR EVEN TOO MUCH AIR

FLOATS MAY NOT BE ADJUSTED RIGHT (TOO LOW) (LITTLE GAS)

OR THE POSSIBLE VACUUM LEAK - DO THIS OUTSIDE WITH A FIRE EXTINGUISHER HANDY (A WET TOWEL MIGHT WORK WELL BEFORE YOU HOSE IT WITH THE EXTINGUISHER!)

INSURE YOU CAPPED ALL OPEN PORTS ON THE CARB AND INTAKE MANIFOLD (NOT THE SWITCHES THAT ARE DEAD) WHILE IT'S RUNNING, IF YOU FIND A VACUUM PORT YOU ARE UNSURE OF, IT WILL SUCK YOUR FINGER TO IT IF IT'S LIVE (BASICALLY, A VACUUM LEAK)

CRANK IT UP AND EITHER USE A *****UNLIT PROPANE TORCH***** PROPANE-NO FIRE! ANY PLACE VACUUM COULD LEAK (HOSES, INTAKE, UNDER THE CARB (MAKE SURE IT IS BOLTED DOWN WELL, ) GET THE PROPANE CLOSE--IF YOU HEAR THE ENGINE REV AT ALL, YOU MAY HAVE FOUND THE LEAK, AS IT IS DRAWING IN MORE FUEL INTO THE LEAK

CARB CLEANER WORKS TOO, DEPENDING ON WHAT YOU USE, EITHER IT WILL REV, OR IT MAY DIE DOWN WHEN IT HITS THE LEAK
