The 1 barrel carb I have is from a 78 GMC truck with a intagrated head 250. I am wondering what the electric selanoid for the idel gets hooked up to. Is there some switch or is a keyed 12 volt like a choke. After I wire it up how is it to be adjusted? Should I just ditch it and put a screw in its place? Sorry for all the questions. Thanks
