Whats the problem?

when you give it half throttle or more the engine starts cutting out and not gtting full power. Whats the deal? Its a 2 stroke.

Either jetting (could be a dirty main jet too), low float level or electrical.

What's the spark plug look like? Have you tried a new one?

I figured it out. The main jet fell out.

Clean the carb first and get a new spark plug. Then run Sea-Foam through it if they sell it where you are.
