    carb ?

    on my demo motor (74 chevy 350) ihave a rochester 2bbl, my question is the idle air mixture screws, timing is close, but with the screws 2 full turns out from bottomed out i cant floor it off idle it will just starve itself and die everytime only when warm. But if i turn the screw in to 3/4-1 full turn from bottom revs up real smooth and put it in gear and the motors spins my 4:56's with no problem. Before i would have to floor it, stop pump it, to get it to rev up then hold to floor. So my ? is this setting ok for the motor/carb a friend of mine said they should be like 2-3turns out and something is wrong but it runs awesome now. So do u think it will be ok i just dont want it to run lean and melt down even faster than what im gonna do to it on the 21st

    The idle circuit you are adjusting is just band-aiding the real problem, which is in the acc. pump shot, power valve or main circuit. You know all you have to do is get in touch with me and I'll walk you through it!!
