Sinergy, I don't think you've given this engine a fair chance before making the above statement. "driesbabe" said he tached 7800 on a Master Airscrew 20 x 10. Poco said he thought that was low for a 65cc, but drisbabe made it clear that 7800 was taken just minutes after starting the engine for the first time, at an higher altitude of 6800 ft. above sea level, and using unmodified factory needle settings that should naturally be set at the richer side. And if that MA prop is that big heavy nylon variety, that would make it even more understandable. driesbabe further noted that his G62 turns a Menz 22x10 at 6300(Standard mag and questionable muffler), but RCIGN1 kinda supports this data by saying his observations were that a G62 turns a MSC 22x10 at 6400 rpm, with open no muffler exhaust at the same altitude as driesbabe! So, in my mind .... driesbabe's 65cc has a 1400 rpm gain over a comparable G62, in exchange for a 2" reduction in prop diameter, while running rich, at high altitude, and only minutes out of the box. Now I know nothing's scientific about this comparison, but I don't think considering all the variables that this is closer to a 50cc performance, as you put it. ... unless you also want to say the G62 is low. As RCIGN1 explained, you HAVE to set up your needles before you can get good readings ... worthy of laying fault on.
