Good Deal!, Not the Messing w/ it----but the Vacuum lines
Should it have been a "injected model", and you had messed w/ idle.....You would have messed up "Base Idle" (factory set, in which the ENTIRE computer system is CALIBRATED TO! If you move idle on one of those....all sensors are OUT OF WHACK, and other things happen because the computer tries to compensate.
Like I said a am not "UP" on yours, but sounds like its close to a "Late CJ 7"
This is what I want you to do, AFTER-AFTER-AFTER You get new vacuum lines on, if you had it Tweaked The Best It Could Be.....A VACUUM LEAK would prevent MAX EFFICEINCY
So this procedure will hurt nothing---on a Carburated Model Vehicle.
I saw this in a Owners Manual, for a "Toyota???" Way Back.
That Rig came w/ this "Spray paint can, looking cap"
The Manual said (basically) This was its use...........:
Rev the engine and hold it at 2500--or so RPM, (do not try to Blow It Up!)
Keeping your foot on the pedal (not withdrawing it until engine hits "0" RPM) This "THROTTLING" could be done under the hood also...using Dwell or Tach Meter [or by ear, by myself, as I do]
When you get to RPM--Put the "CAP" over the CARBURATORThis sucks the Internal Passages Clean, within the carb, using the Engines Own Vacuum. (AND IT DOES A DANG GOOD JOB TOO!!!)
REMEMBER THISWhen you do this procedure.........You "FLOOD" the Carb, Thats OK, Hold the throttle WIDE OPEN and crank on it......It will start really soon!
Always keep a towel and a fire extinguisher handy......a backfire might set the flooding on fire......smother it with the towel, if it should (not happened with me yet!).......Use the extinguisher, if the towel don't work!
When I do this on rigs, I may do it 2-3 times....using a Device that will seal the carb....Or a DRIPPING SOAKING WET TOWEL/RAG/ETC AS SEEN IN PIC BELOW......Next step is adjusting the carb.
On a CJ you must remove the Air Cleaner Retainer
WITH RPMs HIGH (not enough to blow your motor) Slap on the rag, Hold the Wet Rag Down Hard, Till Engine Dies---WHILE KEEPING THE THROTTLE OPEN (seen w/ other hand)
Adjusting the carb is not hard on a CJ, Probably similar on your rig....This link may give you good info throughout....adjusting is toward the end.....YES,....I DO TALK IN CIRCLES, I JUST TRY TO HELP YOU G.I. ......NO LEAVEY NOTHING OUT!
I do have a "CJ MANUAL" including '87-'90 Wrangler...So I sorta maybe can help more if you have problems
Now is this more and better info than your EVIL BUDDIES GIVE?
Don't forget to make me sound "ANGELIC" in "FEEDBACK"!!!
Respond.....I'm going nowhere!
