Carburetor problems

After you try starting the car, look into the carb and see if there is standing gas. If so, I would say the needle valve is gummed up and giving too much gas.


Try starting it by holding the throttle open 50-60 percent, and cranking it a lot. Once it starts, see if it will stay running by you constantly pumping the throttle. Sounds like the time my holley got something in the needle valve and dumped too much gas.

Whatever you do, do NOT keep pumping it. You've already got it flooded from the sound of what you posted. Pumping the pedal will only give it more fuel, soaking the plugs to the point where they won't fire. What carb do you have ? You'll probably need to completely rebuild it if it sat a long time. On Holley & Autolite carbs, the acellerator pump diaphram gets dried out and will rupture when used again, leaking fuel out the bottom of the primary bowl ( secondary too if it's a double pumper). The power valve also has a rubber diaphram that will also rupture, causing it to flood. The needle & seat assembly will stick, this causes fuel to completely fill the bowl(s) to the point where it will flow up and out of the bowl vents (the tall open tubes inside the aircleaner)

Yeah, the sentence in my reply should have read "cranking it a lot" not "pumping it a lot"
