Nice Maxam. You should try one of these on CDI ignition. I found the carb to have adequate fuel flow, and you don't need to sog up the motor by cranking the high-speed needle way back to drop RPMs. On the ground it's a bit deceiving, but in the air if you give it 3-4 clicks rich from peak it works great. Wonder what 6,350rpm on a 24x10 Mejzlik gives you in the calculator. That's what I'm able to obtain on CDI - very impressed with the power on my 2nd engine (first one was missing o-rings all the way around the intake tubes... not cool). I also found no need to limit this carb to 3/4 open, but in general... the carb on these engines is definitely not of good design or quality. It's pretty bad...
