Why does my engine only run on half choke?
When a two-stroke only runs on half choke it is usually the result of a dirty fuel cap, a leaking gasket, a clogged carburetor, or a gunky passageway. In rare cases, it could be the result of a crack somewhere on the engine. You can fix these problems by cleaning the carburetor, removing the fuel, and adding new gas.
