Hey guys, recently, I did an engine swap on my Jeep Cherokee XJ and fitted it with a Toyota 4Y Carb engine, I have not driven the car a lot. But the engine does not seem to idle well. I adjusted the jets on the carburettor and even the idling screw, but when the engine runs for a while the idling goes high, when the engine is cool and i start it the idling seems to be low because if i dnt step on the gas a little it'll switch off. Recently i tried starting it but even if i stepped on the gas, it would just switch off. Now i fiddled with alternator and the idling seems to have gone very high. I really need help on this one, I just cant figure out whats wrong with it. Thanks.
