I have a weber carb, when I take off thru the gears it seems to run ok but starts sputtering and dies! When I am at cruising speed which can be 35mph or 55mph I have the 4.2L motor any suggestions?

LOTS!

LET'S HEAR ABOUT WHAT STILL HERE AND NOT STILL THERE!

PICS OF YOUR ENGINE WITH THE BREATHER REMOVED MIGHT SAY A LOT WITH OUT SAYIN' ANYTHING!

I MYSELF FOUND THAT "TRULY" TUNING A WEBER "PERFECTLY" IS AN ART FORM

I GAVE UP AND GOT A HOLLEYNOW THAT I LEARNED SOME MORE----I THINK I COULD DO BETTER WITH THE WEBER, IF I STILL HAD IT!

"RIGHT OUTTA THE BOX"---PROBABLY AIN'T GONNA DO GOOD

THESE FOLKS WHO SAY THEY CAN TUNE/ JET IT---THE "SPEED GUYS"----USUALLY KNOW ENOUGH TO MAKE IT RUN.I SEARCHED A LONG TIME AROUND HERE FOR A "WEBER KNOWLEDGEABLE GUY"

. AND NEVER FOUND HIM!

READING WAS THE BEST TEACHER---AND STUFF I'VE LEARNED SINCE

I HAVE TO RUN AND ERRAND FOR 30-45 MINUTESI WILL CONTINUE WHEN I ET BACK

I MAY BE ABLE TO MAKE THINGS BETTER---PRESENTLY HAVE A LOCAL GUY WITH A DGEV WEBER WE ARE ABOUT TO PUT STUFF I LEARNED IN USE ON HIS

BACK IN A BIT!

I'M BACK

JUST WANNA SHOW YOU HOW A. NAL I WAS WITH THIS WEBER

I REALLY WANNA SORTA QUALIFY MYSELF AS "TRYING HARDER THAN MOST ANYBODY"

I DIDN'T JUST GIVE UP!

WEBER ADVERTISEMENTS PROMISED A 20% INCREASE IN MPG----I WAS ALREADY ON THAT QUEST FOR HIGHER MPGs TRYING EVERY "GIMMICK" I COULD FIND. LIKE THE OPPOSING MAGNETS ON THE FUEL LINE (THEN MY VERSION, "ATTRACTING MAGNETS ON THE FUEL LINE"), THE OLE TORNADO, ADDITIVES, TIMING CHANGES, THE LIST GOES ON

YOU KNOW, I STARTED OUT WITH NOTHING.I STILL HAVE MOST OF IT LEFT!

THE OLE WEBER WAS NOT JUST MONEY IN MY WALLET, I HAD TO SAVE FOR IT----I WAS EXCITED WHEN I GOT IT

MY CARTER BBDs WERE GIVING ME MOSTLY 14.5-15.5 MPG, WITH AN OCCASIONAL 16-16.5 MPG

WORK WAS ABOUT 40 MILES AWAY, I WOULD NEVER EVEN CONSIDER DRIVING ANY OTHER VEHICLE, AND MY 15 GALLON TANK FORCED ME TO REFUEL, USUALLY, EVERY OTHER DAY ( I KEEP A RESERVE GERRY CAN ON THE BACK)----LATER, I INVESTED IN A 21 GALLON POLYETHYLENE TANK. ONE OF THE BEST MOVES I EVER MADE!

I'VE HAD 5 CJ 5s IN THE PAST AND NOW HAVE A '77 CJ 5 AND A 1946 WILLYS ALSO---STARTED DRIVING ON THE ROAD IN '81. NEVER CONSIDERED ANY OTHER VEHICLE AS A PRIMARY DRIVER---ANYBODY THAT KNOWS ME CONSIDERS MY JEEPS AND I AS "ONE"

I KNOW THE CJ WELL!

BUT THAT DANGED WEBER---I READ SO MANY SITES--TALKED TO SO MANY PEOPLE---TALKED TO THE PEOPLE SELLING ME PARTS---TALKED TO THE LOCAL RACING GUYS---BOUGHT AND READ BOOKS

FOR OVER A YEAR---I MADE JET CHANGES (AND OTHER CHANGES) TO THE CARB

I KEPT REAL ACCURATE RECORDS OF WHAT I DID (LIKE 11 PAGES, FRONT AND BACK) (HERE'S SEVERAL, SEE PIC 1)---I KEPT UP WITH MPG (EVERY OTHER DAY)---I'D EVEN DRIVE OUT A TANK, JUST TO SEE IF I STRUCK GOLD WITH A PROMISING COMBINATION---I KEPT UP WITH ANY AND EVERY THING I DID TO THE JEEP, WHILE I WAS AT IT. JUST SHORT OF THE WEATHER EACH DAY

I PERFORMED PLUG CUTS SO OFTEN, I WAS SCARED I'D STRIP OUT #1, SO I STAGGERED IT DOWN THE LINE.

A PLUG CUT IS WHEN YOU DRIVE AT "A SPEED", FOR LIKE 10 MINUTES OR SO (I DID, ANYWAY) CUT THE KEY OFF---PUSH THE CLUTCH IN---COAST TO THE SIDE OF THE ROAD---"PULL A PLUG" EXAMINE IT FOR BEING "TOO RICH"--"TOO LEAN"--OR A GOOD BURN IN-BETWEEN

THE KICKER HERE IS "IN-BETWEEN" SORTA-KINDA LOOKS ALL THE SAME (AT LEAST TO ME). THIS IS WHERE ONE MUST SELECT THE THE BEST JET----THERE ARE ALSO "AIR BLEEDS" WHICH IN COMBINATION WITH A JET AND EMULSION TUBES, TURNS THE AIR/FUEL MIX INTO, WELL, BASICALLY A "FOG", FOR LACK OF A BETTER TERMALL OF THIS IS A COMPLICATED BREW

PICS 2 AND 3 ARE PICS OF "GOODIES" I STILL HAVE, AFTER GETTING RID OF THE CARB. BY THE WAY, I HAD THAT TOP OFF SO MANY TIMES, I STRIPPED 2 OF THE SCREWSJUST THESE GOODIES ALONE, COST AS MUCH AS THE DARN CARB

THEN THERE'S THE BOOKS---HERE'S A PIC OF ALL I HAVE LEFT---MINUS THE CARB---MINUS A PACK OF PAPER OF CRAP FROM THE INTERNET (PIC 4)

NOW THE OBJECT OF THE GAME FOR ME WAS MEGA MPGsI WAS NOT GETTING ANY BETTER THAN MY BBD---AND I WAS PULLING MY HAIR OUT---I HAD JUST AS MUCH TIME FOOLING WITH THE WEBER AS I HAD WORKING AS A PLUMBER!

THE WHOLE KEY TO MPGs IS GETTING AS CLOSE TO A 14.7 TO 1 AIR/FUEL MIX, AS POSSIBLE "MECHANICALLY" SETTING UP THE CARB

A NEW CAR HAS A COMPUTER THAT CAN KEEP IT ALMOST ON THE MONEY--ALL OF THE TIME

WITH THE CARB, IT'S GETTING JUST THE RIGHT PARTS WORKING IN UNISON, TO MAKE A CARB DO THE BEST IT CAN. USUALLY "SET" TO WHAT THE VEHICLE DOES THE MOST (HIGHWAY CONSTANT SPEED---RACING---POWER) USUALLY YOU DON'T GET IT ALL IN ONE PACKAGE

NOW THAT I HAVE THE HOLLEY AND FOUND OUT SOME REALLY WELL EXPLAINED STUFF, EVEN A TOUCH OF THE MODERN CAR----I GET 18 MPG!

NOT EXACTLY WHAT I WAS GRABBING AT----BUT IT'S 3 MPGs BETTER THAN THE BBD!

I SHOULD BE HAPPYI WANT MORE!

IF YOU HAVE THE WEBER 32/36 "PROGRESSIVE" CARBONE MUST 1ST GET THE PRIMARY BARREL TO PERFECTION----BEFORE YOU CAN EVEN THINK ABOUT SCREWIN' WITH THE SECONDARYTHE SECOND BARREL MUST "COMPLIMENT" THE 1ST ONE IN "MIXTURE", AS IT OPENS

YOU WOULD TRIP OUT, IF YOU SAW HOW MANY TIMES, I FLOORED IT, AND IT FELL FLAT ON IT'S FACE AS I ATTEMPTED TO JET IT RIGHT

LOOKING BACK. IF I HAD THE "TECHNOLOGY" I USED ON MY HOLLEY, I COULD PROBABLY MAKE THE WEBER WORK A WHOLE LOT BETTER

ARE YOU BORED NOW?

WANNA HEAR MORE?

THE WEBER BOOKS ARE INFORMATIVE---THE HAYNES EXPLAINED A LOT---THE DGEV SECTION WAS NOT THAT GREAT---BUT LOOKING AT HOW THEIR "FAVORITES" OR MORE POPULAR CARBS, I WAS ABLE TO LEARN MORE ABOUT HOW THE AIR/ FUEL MIX COULD BE "MIXED" USING DIFFERENT PIECES, FOR DIFFERENT (I GUESS "DURATION")---SPEEDS--RPMs---ETC

IF YOU ARE GONNA BE A WEBER GUY--BEST GET 'EM AND START READING!---IT'S REAL SCIENTIFIC----AND BORING----YOU WILL NEED THIS KNOWLEDGE (AT LEAST HOWs AND WHYs) FOR 2 REASONS----ONE YOU'LL BE WELL ON YOUR WAY, WHEN IT ALL "CLICKS TOGETHER" IN YOUR HEAD!YOU MUST BE KNOWLEDGEABLE ENOUGH TO BE ABLE TO "DELETE" MIS-INFORMATION THAT WANNA-BEs FEED YOU! DOING THIS "RIGHT" WILL BE A TASK---JUST HAVING IT RUNNING, WAS NOT ACCEPTABLE TO ME

I KNOW I'M NOT THE AUTHORITY BY NO MEANS---I CAN GIVE YOU SOME OF THE "SUPERB" INFO I HAVE FINALLY STUMBLED ACROSS THAT WILL DEFINITELY AID IN TUNING A "PERFORMANCE TYPE" CARB

ARE YOU "IN" OR "OUT"
