Title: carb high idle
Post by: wdstylr on November 27, 2007, 09:20:48 AM
i just put a holley double pumper (650, manual choke) on my truck i have not hooked up the choke yet but I did rig it where it will not move. my truck still seems to get stuck in high idle until it warms up. my question is even though i have the choke flap all the way open is there any other mechanism on the carb that would cause it to idle fast until it warms up. if so how can i deactivate it?
any help much appreciated!
