Thanks for the info. I have to say I have not had these problems with both my on and off road BP engines. You can even ask Steve (Birel8) on this thread, he has finished behind my BP many times last year ( Steve ). Now whether or not BP will have engines at the top of the worlds of euro's, I don't know or care. What I do know is the engines are working very well, very fast and dependable, and priced much better than most of the others.
