Default Re: GR Pro 50cc engine

Single cylinders do shake more than the twins but yours sounds like it set way to rich. Is your choke working when you are first trying to start it? Because it sounds to me like you compensated for the choke not closing by turning the needle out so far that it didn't need the choke.

After you start the engine and it warms up have you tried adjusting the needles and getting it to run perfect?
