The hot thing in the gas engine forums are the 30-35cc rear induction engines and most have a pyramid type reed plate assembly.

I wonder how viable it would be to use the reed plate block from one of these in a Ryobi?

The DLE 30R would be the easiest to obtain but the reeds themselves are possibly marginal in this engine?

From Tower you would have to buy the rear induction conversion for $15 to get the assembly? Tower/Hobbico is not exactly with the game on the spare parts as you cannot get the reeds themselves but there are other sources like Valley View and individual sources or you can make them yourself?

What about crankcase volume if you have a flat backplate with a hole to mount the reed plate sticking inside the engine?
