paul when you say it "dumps fuel" do you mean it has gas coming out of the venturi so much that it floods ? if so then yes it sounds like the needle valve in the float chamber is sticking open or the float is holed,flooded and sunk leaving the valve open all the time

sounds like your needle& seat is stuck open. There are rebuild kits out there on Ebay, but, I think Duane Foley has a stock of them.

This can also happen to Solexes due to heat expansion. If the fuel dump happens when the engine is turned off warm, make sure the top plate gasket is okay and the screws are pulled down tight. On warm cars, heat off the manifold can cause expansion that pulls cooler air right into the float chamber and pressurizes the fuel right down the chute minutes after the engine is turned off. You also sometimes see a surging/stalling effect with hot Solexes that is mistaken for vapor lock, (which is a separate and real problem). Same answer for this, tighten the screws and snug the carb to the manifold, but don't get carried away with the latter or it will warp.

I took the top of the carb off and the needle valve was clean but the float was filled with gas so I took a good float off another solex and now the car starts beautifully, idles for about 3 seconds and dies. If I pump the gas pedal it will stay running but barely.....any ideas???

BTW
I also took the gas line off the carb to see what the flow of fuel was like from the pump and it half filled a smaller peanut butter jar in about 30 seconds.

Still sounds like the carb needs a good internal cleaning.
