OKC, OK
Either there's no free play in your throttle cable, or it has an air leak. Make sure the carb is tight on the manifold and the manifold is tight to the cylinder. It could be a leaky crank seal, but most likely it's not that.

Good luck in your search!

What was said above, or it could also be that your clutch isnt fully disengaged.
After shes cooled down, let out clutch and pull a 16th inch of the clutch cable through and tighten it again.
If none of this works, I'm afraid theres nothing else to my knowledge to help you.

Air leak sound right, intake, base gasket or case gasket between the half's. Also look for fuel under the mag cover and below the small gear on the right side, if you find fuel you have a crank seal leaking.
