I have a Mayhem ST with pretty low hours. The first part I had broke was the clutch. I repaired and after it sat for awhile, now the drill starter will only periodically crank the piston. The hex doesn't appear stripped and it is spinning. Isnt this a hex bolt linked directly to the piston? How could it spin w/o turning over the engine. Any help would be greatly appreciated. I finally got the time to bash and never got warmed up. Plus my truck is still full of fuel. Also, has anyone had to beef up the steering servos, they seem a little undersized?
