Hi, have just installed an aisan carby on my 3f, the previous owner had a holley on it.
It just wont idle right. I have got it to the stage where it wont stall but the idle mixture screw is about 4 turns out and it smells like its running rich. Idle fluctuates from 600 - 1200 rpm and has a misfire.
I have all the vacuum ports plugged except for the choke breaker and dizzy advance. The fuel is half way up the bowl window. Fuel cut solenoid is working.
I gave it a quick thrash around the block and it seemed to run good. No hesitation and good acceleration.

I have tired the method described in the fsm of adjusting the mixture for the highest rpm, then setting the rpm with the idle speed screw but i still cant get it right.
Any suggestions?
