Thanks

Well I thought by now many others would have chimed in. But, yes 4 strokes are very happy inverted. Two considerations: 1. Make sure the tank centerline is in line with the carb spraybar, to insure proper fuel draw and delivery; and 2. Incline the engine slightly to have the exhaust valve at the lowest point of the engine, to insure that excess fuel and oil can escape and not cause hydraulic lock. Good luck.
