Tim, I stand corrected, you're right it was T-wink who was doing the r/c reed engine experiments.

In regards to Clint's and Combat's reversion theory: In a 4 stroke you get fuel and air inertia travelling down the intake and then the intake valve closes while the charge is still travelling and wants to slam into the intake valve. If the engine is designed properly with the right valve overlap and intake and exhaust lengths you'll get a scavenging effect where the negative exhaust pulse will draw in more intake charge than would have otherwise come in if we merely relied on atmospheric pressure, thereby making more power. If the components are mismatched and don't work well together and the valve overlap is not proper you'll have the intake open after the negative exhaust pulse has gone and you'll get a positive wave travelling back up the exhaust passages toward the exhaust valve. This wave will prevent some of the fresh charge from the fuel/air pressure wave travelling toward the intake from entering the cylinder thereby resulting in a flat spot in the torque curve at a certain rpm. In a 2 stroke and especially with a reed valve things are probably a little different but still I would guess that with the reed valve fluttering and "making waves" the fuel/air flow is disrupted. SOLUTION: Why not make a flat twin (here we go again with the r/c reed engines heh heh) .049 reed engine feeding off the same carb but firing alternatively. This way when one of the reeds is closed and the wave wants to push the fuel/air mixture back out through the carb, the other reed is opening and wanting to suck in the charge. And so you'll get a scavenging effect. You'll get the fuel into the engine that would normally come in due to the presure differential in the crancase vs. the pressure outside the crankcase on the other side of the reed valve PLUS you'll get the extra mixture that'll be pushed in because of the wave created by the other reed valve that wants to push the intake out back toward the carb. Therefore a .049x2 reed valve twin with an r/c carb should work much better than a single r/c reed engine.

Anyways, this is just a theory. What do you guys think? Please rip it apart.
