Alright heres my problem. I have an 86 305 with a q-jet carb.(not sure on which one it is) When i go to start the truck after it has been sitting for a while the choke kicks in and my engine revs high. After a couple mins i tap the gas and it revs down. The carb was rebuilt when i got this motor and we swapped the electric choke off of the carb that was on my 85 4.3L and put it on this carb.
What do you guys think the problem is.
Also if anyone has a good condition holley or edelbrock 4bbl around 600-650 cfm i might be interested. Im sick of this q-jet.

Thanks guys
