    The litetek kit replaces all the carb seals. I just done mine and it has made it so much easier to start. It idles a lot better now as well. It doesn't have the jets, seats and needles.

    Sound like an air leak if you need the choke on for it to run.

    Is it an a model? If so the only vacuum lines are from the carb boots and to the fuel tank. If mine is disconnected from the tank it doesn't idle.

    Its looking like it could be overfueling, pulled the carb out and bowls off checked the floats and it dumping fuel in when the needles are shut.....Could it be as simple as needle and seat?
