Turn out 3-4 turn main needle at carburator.

Back off compression screw and prime engine carefully and turn propeller fast while you are turning compression screw 1/4 between 10-12 turn of propeller until the engine starts.

When the engine are running, adjust the compressionscrew until the engine are running fast.

Overcompressed make the engine slow or oscillating cause too high compression and early "ignition timing". Undercompressed make the engine rough and slow cause "later ignition timing"

Then lean out the main needle until the engine are rough and turn back 1/4-1/2.
