I am glad you asked. No I do not sell engines. I have many that are ready to be test run. I do not like to run them in cold snowy weather. As I read this conversion stuff, I just got the bug to do a few. Well I got to many now to finish. Thats ok, because I can use parts like on the Homelites to replace parts when I make a mistake like forgetting to remove the little ball that is spring loaded on choke shaft. It ruined one of my best engines. I can fix it with spare parts from the extra partly done engines. I have been helping my Grandson a lot with RC airplanes. He is in collage, but we get together quite often. He in turn is getting other collage kids into RC. It is real rewarding to me. I do help about everybody in the area on engine powered devices. In turn I have had some pretty good power products that people do not want. One was a Echo string trimmer, because the woman who owned it bought another one that started more easy. The Echo has very high compression. I do not understand how I come buy this stuff sometimes. I bought a Like new SuperTiger .90 with nice spinner and prop for $2...thats right ...two dollars. The head was missing...do not know why, the rest looks perfect! In the future there will be more give-aways, I got too much!!!! Capt,n
