A fuel problem is what did my engine in. Engine detonation burned the top of the piston. The OS will run just fine with a good set up. There are more than a few pilots on here that will tell you that the OS engine rod will not last at max rpm. But then I've had a lot of other brands of engines blow a rod too. I like the OS over any of the other brands except BV's.

Give it a try and tell me what your experiences are.
