Thanks for the approval! So have a question gotta 68 impala with a 350 4 bolt Main replaced the distributor to an hei and went to a edelbrock 650 avs carb with electric choke. Having some running issues wirh the idle when its cold it wants to sputter out and die but when Its warmed up the idle shoots way up and wont come down. Its very veigh but thats whats my problem is need some help more then happy to answer more questions to hopefully get more info

Todd Nyquist: Choke needs adjusted. Its not disengaging all the way.

Jonathan Jackson: How many ways are there to adjust the choke? As far as I know Ive been playing with the black cap on the passenger side of the carb to adjust from lean to rich.

Ronald Johnson Sr: You need to start at your lean screws on the front of your carb 1st take them both in till they bottom (not tight or youll ruin the orifice, then turn each out 3 1/2 turns youll be close enough to set up your idle in park at 950 rpm, in drive you should be 725 to 750 rpm, choke if set correctly start at the straight up position and turn your choke cap 1 notch to the right ,
