what happens is it starts fine and will run good for 2 to 3 min then the backplate get losse and it gets warm and all kinds of oil dumps out of the backplate and it starts to lose power and finaly it will just stall when i hit the gas befor the back plate was getting lose it never got hot and it would run great right now i have been running it a lot at night and it has been nice and cool outside with low humidity and 55 outside and 20 to 40% humidity thats the only time i realy get time to play with it
