On my first trip to the track it ran alright for about 1/2 a tank, but then suddenly something happened, it had no power and the sound changed. It sounded like it was bogging pretty bad and then just quit a few seconds later. Tried to restart it, and I can get it to fire if I give it about 1/2 throttle while cranking, but the second I let off the throttle it dies. And while it's running at 1/2 throttle it's revved up pretty good, have to keep the wheels off the ground and all that. It also doesn't seem to want to rev as high as normal, either.

I've taken it apart, nothing is obviously wrong, but same result when I put it back together. Even reset the carb to factory settings, no difference.

I've never seen this before, not too sure what to do. Any advice would be appreciated..
