Ran another tank through mine this one mostly around half throttle and above. All cylinders were around 180 most of the time and i was using a 24x12 2 blade prop.
The rpm at half throttle was about 5,000 and it went up to around 6000 near full. As I approached full the rpm dropped off.
As i reduced the throttle .the rpm would pick back up. Other than that the throttle response was pretty smooth.
I have watched the tuning video Saito has and not sure how to apply it to the gas motor.
I reduced the low speed until the rpm dropped and the opened a half turn.
Adjusted the high speed a little but did not want to get it too lean.
Any advice on how to go about the tuning would be appreciated.
Thanks
Kevin
