rochester question
I have 1981 chevy c10 with a 305 and a rochester dual jet 2 barrel carb. I have heard that there is a way to knock out some plugs that cover adjustment screws but don't know how to get the plugs out if they really exist. Any advice would be much appreciated!
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
