Question about 1978 Chevrolet C1500
Manually operate the choke mechanism and watch to make sure it fully releases. Quite often mistakes can occur when putting the pieces back together and it won't fully release off fast idle.Are you absolutely positive that you didn't forget an o- ring or ball when you put the carb back together? Is there any chance there is a gasket upside down? Could the power valve be in wrong? These types of things could create that problem, there is too much gas going through your idle circuit.What happens when you turn in the idle screws? Are you sure about the timing? I don't have specs for a 1/2 ton but all the specs in my Chilton give me 6 degrees in California and 8 degrees everywhere else. These numbers cover all models of cars for a 1978 350. Hope this helps.
