Take a cut-off wheel and remove that danged 'spark arrester screen' and pitch it in the trash, that's what was wrong with my 044 once, has ran perfect ever since.

This right here has been the answer on many saws people have brought me. If they make the fuel mix rich (novice erring on the side of caution when mixing fuel/oil), then you plug the spark arrester screen.
Whenever I lend out a 2-stroke. I always lend out a can of fuel I mixed using premium gas and a quality 2-stroke oil, mixed to the correct ratio.
