AS Motor 2 Stroke

Mower doesn't regulate RPM well.

Runs fine on Full Speed but doesn't regulate or run fine on idle.

I have the idle screw turned all the way in (high idle) but the rpms are to low.

What I've done so far:

New OEM Carburator

New OEM Coil (no spark when warm)

New fuel and lines

New Sparkplug (NGK)

New Air Filter

Checked Piston, rings and zylinder wall everything is fine

Can someone tell me how to adjust the air flap on this motor?

What's the max rpm for this motor?

Thanks for your help
