Hey, I chatted with the local dealer today we looked at the exploded views, I assumed the engine was a lot like the shindawia in design but they are quite different. The stihl does not appear to have a reed/flapper valve. The shindawia has two. the parts diagram shows a very small light crankcase, it has a small flywheel with fins on the front and back! The module even looks small. I believe you could face off both sides of the flywheel for more weight reduction. The back of the casting has tapped ears that could be used for a mount I could only see two on the picture but I believe there's three or four. As far as four strokes go, this engine will be light. Now we have to see if it will turn a prop!The dealer is going to see what he can do about getting me a power head.
