Re: Really bad milage
I fooled around with a truck when I was going to tech school and of all the things I tried actually richening up the carb made mine get better gas milage .not to say yours is , you can try it either way ... That being said Does your truck have a vacuum advance ? check to make sure it is in fact working ,that will suck a pile of milage out of it if it is not .. and make sure it goes to manifold vacuum... on the carb a rebuild cant hurt first , then start changeing jets and drive it for a week with each change ..... I would still adjust the idle mixture with the engine hot choke off til it pulls the highest vacuum reading ....
