when its on ground it acts like its flooded.have to pick it up to start cause the wheels want to turn like the throttle is stuck but its not red lining i drop it it takes off like its at a 1/4 throttle or less at idle.and when it does go the first good hit shuts it off.i justed replaced the clutch and it ran fine.it sort of took a hard hit on the right rear side and it turned off and thats what startsd this i think.whats not allowing it to sit still at idle?clutch maybe?something is not allowing it to disengage
