I have sent two engines to Hummel Engines. One needed every interal part replaced and he got it as a basket case. The other had to have a complete case replaced along with bearings. Both times I spent around 2500 dilivered. I even sent Scott the paint and he painted these engines the color I wanted. He told me he has never painted an engine purple. The first engine I put around 200 hours on it before selling the airplane and that engine was running great when I sold that airplane. The second is still in service with around 50 hours on it now. It is not broke in yet. If not for the vw, I would have stopped flying. Two strokes are not for me and GA engines are out of my price range. The vw fits perfect for what I want in an aviation engine.
