Hi

I just was trying to start my tornado bb earlier but when pulling the pull start it seems like it only turns the engine over once or twice. It feels like it grabs and spins the engine one time but then loses grip and then it becomes really easy to pull. I have just recently put the aluminum exhaust on it but it still ran afterward. Yesterday it was doing the same thing but if i pulled it fast enough it would start up and it still ran good. I took the pull starter off and it didn't look like it had any problems. Also the little nut the is on the shaft spins the one way but not the other so i don't know whats wrong.

Thanks
