I have an 89 Caprice Station Wagon, with 307 (olds) engine, and
automatic trans. It runs well, except that it stumbles whenever I
take off from a light or other stop. I have to always double pump the
pedal or the engine dies.
My thought is that the accelerator pump rubber is worn and it needs to
be replaced. I dont want to get into a complete carburetor
rebuilding, since the engine runs well both at idle and when driving.
Does anyone know if I need to tear the whole carb apart to replace the
accelerator pump, or can I just remove a few screws without removing
the whole carb and ripping it apart?
