Hello everyone! I'm new to the jeep comunity and have a carb problem on a 4.2 carb, 90 yj.
Is it a typical problem that the solenoid for the idle needle fails? jeep runs fine except at idle. un-plugged the electrical for the solenoid and no change.
This is just my opinion but I think that you should take it completely off and use it as a paper weight, and order an Edlebrock ASAP! Again these are just the opinions of a shade tree mechanic but there are way to many parts and pieces on the stock carb that can have problems.
He's got a carb. Remove the carb, set on bench, and install a MotorCraft 2100 or 2150 using a Mr. Gasket adapter plate. Should fix your problem, and future problems.
OOOoooohhh Yeah!! i guess i should stop drinking my first beer.. What was i thinking, Carburator? IAC?, then what was the electrical solenoid?:???:. regardless, this beer break is over.
Ran a torch tip cleaner through the idle tubes (had to remove the venturi cluster first). Felt no real resistance pushing the wire. Didn't think there was a chance in hell that what I did would actually fix it. But it did!
I'm not carburetor wise.
Thanks for the replies, It's what makes this internet so damn cool.
still ditch the carter. bounty's right , i put a 2150 ($15.00 at junkyard) on and a nutter in the driveway ....threw away 30 miles of unused vacume crap and it runs like a top .
