You sure it's "too much gas" or is it "not enough air"? An engine needs both in the correct amount to run good. When you turn the gas off, the engine runs until the last of it but just before it runs out, it has very little gas in the carb going into the engine. At that point, the ratio of air to gas goes up. That's whay I'm asking if you're sure it's getting enough air.

Are you running it with the choke ON or OFF..?? It probably will not idle till it is completely warmed up and the choke off. Make sure the carb is seated properly into the head extension and the clamp is snugged up well.
