Hi

A friend of mine built one of the original kits, and had the engine inverted. It was a K & B 40. He started the engine with the plane up-side down in a cradle and adjusted the engine just slightly to the lean side, just a hair. You will have to experiment with engine settings to get it right. he flew it quite a bit and never seemed to have problems with the engine. It was a nice flying plane.
