Runs rough and stalls at light
1985 Chevy Suburbin...starts to run rough and stall while sitting at a light...just changed the carb from a quad jet to a Holly with a electric choke..has a mechanical fuel pump...the other carb (quad) was giving me problems, that's why I chnged it...this is a 350 small block...the engine has 25,000 miles on a rebuilt engine which was running fine...the reason for the carb change is no choke on the quad and could not get a manual choke to work wright. I had this problem with the other carb.
