I have the engine on a nice stand and travel to engine shows and sometimes start it up. I may put on a J3 or a Fly Baby someday. It is a engine you just do not want to hurt much. Look up this... Kavan50.com or Google it. Then I think you will see why I want to keep it very nice. Will run it on the first time on spark ignition (was Glow)...very soon. Capt,n
