Check timing to make sure it isn't advanced too far, this can sometimes simulate a lean condition.
Check cam timing, long shot, but engine is newly rebuilt.
Do you have an EGR? and what kind of shape is it in?
To check for leaks at a gasket, start the engine, let it idle, and spray carb clean at the gaskets. If the engine tone changes you have found the leak. BE CAREFUL.
This should narrow it down to the carb.
Not sure about the make up of the carb, but is it capable of flowing enough for your block?
Hope this helps... |
engine temp: higher than it should be, but not overheating.
timing... set right.
cam timing... pretty sure thats right... it ran with this set up before i changed the carb.
EGR... currenlty blocked at the intake and header port... but under reconstruction with new valve and tube on order.
Vaccuum leaks... havent found any more with the method you noted, i think i have them all sorted out.
99% sure this carb is right for the jeep... a bajillion other jeepers swap to this unit. what i dont know is if the others that do the swap have the same headers, this exhaust may be flowing more than a stock exhaust manifold... my thoughts are to increase the jet size.
i have never installed headers before, is it possible that the paint that is peeling off is retaining heat in the upper tubes? its almost all cracked now and a lot of the paint is gone. i dont let it run too long usually cause i am paranoid about burning up the motor.
