My 06 Trx250ex just got up and running yesterday after a project rebuild for the clutch and some other small components. It runs now but, it stops delivering power after I pull the throttle to hard and usually stalls out. My friend noticed when it did it, it spewed gas out of the exhaust. I'm thinking the carburetor is flooding however my friend says it needs a rebuild. I'm hoping that there is an easier, less expensive solution.

Any advice, help, anything you guys know would be nice. I really want this thing running back at full capacity.
