    So far no one has mentioned fuel pressure and float adjustment. Lotsa people use electric fuel pumps and you need to be sure pressure does not go over 5 psi. If float is leaking or now adjusted correctly car can run terribly rich--if it runs at all. And gas can leak out between cover and body. Usually fixes are fairly simple (for others---not necessarily for me!)

      As Jeffry stated, using electric pumps can push the pressure way over ideal levels for our old style needle and seats. I use a cheap fuel regulator and dial them way back as our cars were intended to be used at very low (by today's' standards) settings.

        Fuel pump was replaced. I notice stains on the driver's side of the carb and paint is stained or melted away on the manifold. I tightened the screws and wiped it clean to see if those stains reappear. Could it just be a worn gasket? There is no ethanol-free gas here on long Island.

          Yes it could be as simple as a worn gasket. I had a 1962 Lark with a 4 barrel and the carb would have to be primed if it set for just a few days and it had a faint smell of raw gas when you opened the hood. New carb gaskets solved the problem.

          Hope this helps.

            I've been informed by a carb specialist that a rebuild @ $315 is called for. Unfortunately, it's not in the budget right now and also it was adjusted, but not rebuit. when the engine was redone. it was rebuilt, however, when I got the car some eleven years ago. I don't want to drive it less as it's one of my favorite activities. Maybe I'll just sell the Sky Hawk and but a used motor boat. What could possibly go wrong with one of those?
