    Hi, My china engine was pretty reliable until it was
    not used for a month, never ran the same after.
    So I searched the forums and found my air
    filter was full of fuel so I cleaned it and it ran good
    once or twice then would not start. Bent the lever
    in the fuel bowl to make the needle seat to stop the
    fuel leak. Ran good once but wont start again.
    Played with the e clip setting, ran good twice
    but wont restart.

    Thought about buying new carb but I know this
    one is fine once fixed. When it does run at full throttle
    it has to have the choke half closed, if choke is
    opened all the way the engine immediately stops.
    Vapor lock fuel tank? Any ideas? :rolleyes7:Thanks.

    that carb never works right no matter what. very poor design.
    Buy a Mikuni or Dellorto

    running only on half choke is either something blocking main jet, or an air leak

    air leak is usually at the intake, but don't forget to check the crank seals too

    same old, same old, tear the thing apart, give it a good clean and blow out, re assemble, enjoy...

    drain fuel if you think its going to sit around for a while, next time

    I discovered there is no spark, so after I fix that problem I will continue with the carb problem.
