Default RE: Tanaka 21cc conversion ?

Hi W8ye,

I think I've run across your comments on my thread about converting Saito (and other) nitro engines to gasoline usage. So, I received a free plane from a guy at our field who doesn't like to do repairs after a hard landing. It's a Great Planes Katana 50. The cowl will need some repair, sanding, and bondo to make it presentable. Unfortunately, it's yellow. Now, yellow fuel proof lustercote (Top Flight) is known to need 10 cans of spray to cover anything. And it doesn't react well to primer either. So, I'm going with a gasoline engine and rustoleum paint to get around that hassle.

I have a Tanaka 21cc gas engine, unconverted yet, just like the one shown in this thread. Should be a good candidate for this plane. HOWEVER, I noticed there is no reed valve for the intake. Does it have it's own porting and thus not need reed valves? How does it get around blowing air back out the intake from the crankcase? Or, is it just missing from the pictures?

Any insight will be helpful.
