Thanks for the help guys!! The head bolts are tight. As for the fuel I make my own. I work for a paint co. so I can get all materials free. Methanol is paint grade, Nitro is pure, same as any fuel manufacturer gets. I use straight castor for the oil. I am using the fuel in other engines that have no problem. As the end cap of the muffler came off in flight, I am awaiting a replacement before I can try setting the carb again.

Flyboy is it possible for you to scan the instructions and send to me? I did not get any with my engine.

Thanks again

Doug
