Yea...I am thinking I will go ahead and convert another 31cc Ryobi. Maybe this time I will spring for a Frank Bowman ring. I would have to go back and look at some of my old post, but I believe my last Ryobi was swinging an APC 18x6 around 7200 RPM and it may have had the potential to do even better with a walbro carb instead of the Zama, but I had no issues with the engine or the Zama carb and it ran so nice I just kinda left well enough alone because I wasn't really looking for the Rascal to be a hot rod......just a big gentle flyer I used to drop parachute guys from.
