Sounds like it may be running lean on you. I'd try riching it up some and see if that helps. What engine is it?

Okay, I'm not really familiar with that engine but I'd say try riching the engine up a little to see if that solves it. I'd imagine it's probably new and the engine hasn't quite been broken in yet. The proper break-in procedure is important for the longevity of the engine. Refer to the manual to see the specifics on how the engine must be broken in. Try turning the needle valve counter clockwise, in quarter turn increments at a time to see if that helps. Opening it just far enough where you can open the throttle without it bogging out. Don't worry too much about speed because it'll eventually get faster once the engine is completely broken in.

Good luck =)
