Chainsaw Repair

JMO I would do the  FULL THROTTLE in wood 3-5mins per owners manual. Just keep making cuts with bar buried if you can and see.

straight from owners manual = The following steps should be taken when the chain saw
is started for the first time or when outside circumstances
change (fuel, altitude, air filter etc.): Start the engine.
Accelerate the engine to full throttle and saw a number of
cuts in a thick log (3-5 min.).
The chain saw must be run (8,000 - 12,000 rpm) the entire
time so that the carburettor can adjust itself. ------- 8K to 12K must be kept up in rpm in the cuts.
