Car54: I think the engine (MB290) would work well in a Ultra stick 120. Like any conversions you want to hacksaw & grind off any metal and other parts you do not need on engine. Gryohead... That is a Homelite 25cc Glow engine I am working on. I will post a photo. I am going to try 3 ways of running it. Straight gas....straight glo fuel and then a mixture of Gas & Glow fuel. I think straight glow fuel will produce most power. Capt.n
