I'm not sure what I'm doing wrong but there are a few things I can't figure out on my 4 stroke saita 82. It is about a month old with a gallon or so through it.

My throttle is connected properly by which I mean that the carb opens up gradually while move up the throttle stick... I tuned it on the ground and all but the weird thing is that when I'm flying it, I can't tell the difference and feel no different between half throttle and full throttle. It seems as if the engine is going max RPMs at half throttle and anything after that, I feel nothing.

What am I doing wrong in my tuning?


Also one more thing on my Idle and i dunno if this has anything to do with the above problem. My plane is a 46 size Phoenix Yak 54, I have the 13x7 APC prop on the 82 and if I idle to where the engine is running wee, the plane wants to taxi and does not hold. If I trim the idle down to where plane does not want to taxi, the engine seems to have a hard time idling, shaking the plane like putt putt putt putt.

Help please .
