Thanks for the info. I bought the plane from a friend of mine, it has never been flown. Has a new fox 45 bb engine. When I took the cowl off, I noticed that the fuel tank plug was close to a inch higher than the crab throat. When I was running the break in. fuel continously dumped from the carb, and while starting too much fuel would get in the engine cylinder and you couldn't get the prop to spin at all. If I turned the plane upside down, it would spin easily. I have to either lower the tank or rotate the engine to either 90 degrees or upright. However: once I had it started I could turn it over and it would keep running. There's not alot of room inside the fuse for cutting to lower the tank. I like the looks of the cowl, but not sure I want to hassle with starting the inverted engine everytime I want to fly. Also thinking about updating to the Saito engine and using the 45 BB in a different plane. If for nothing else, it gives me an excuse to buy another plane[sm=wink_smile.gif]
