Re: Engine Problem (sorry)
A couple things to check- first, check or replace the gasket between the carb manifold and engine. They are notoriously bad. Second, make sure the slide is in the right way around.
When you look in the carb with the throttle closed, you should see something (silver) blocking the intake opening, and when you turn the throttle, it should move up, opening the air intake on the car. If you look in there and it's partly or full open chances are the slide is in backwards.
