    Carb Problem

    I have a '65 L76 that is all stock. When I bought the car 13 months ago, the carb was in bad shape. At that time, I had the carb vatted and rebuilt. Since the carb was rebuilt and the intake manifold leak fixed, the car has been dependable, always firing right up. Ahh, the sound of those side pipes!

    In the last two months, as the car sat in the garage, a small pool of gasoline has been appearing under the carb, around a driver's side intake manifold bolt head. When this showed up, the engine became tough to fire up if it had been sitting for a few days, requiring a lot of cranking and pumping the throttle. But, it would eventually fire up and run fine.

    Last weekend, I cleaned up the small puddle of fuel on the intake manifold and tried to start the car. The engine turned over fine but would not fire this time. Finally, the battery gave out. When I charged up the battery and continued to crank, the starter died. I surmise that the replacement starter was on its final legs anyway (I have a rebuilt original to replace it).

    What I need to find out is what you think is causing the fuel leakage...which causes the engine to be "hard" to fire up? -Clark

    Clark -- a puddle of gasoline on the driver side intake manifold sounds like it could be the accelerator pump diaphragm. That would give the hard-to-start symptoms (nothing to squirt in the throttle bores).
