Can`t agree with you there! A WELL modified saw is like the factory should have made it, but didn`t of different reasons. The porting is more ballansed, carb venturi is the correct sice, muffler is more open to prevent exhaust blowback, sqish clearense is correct, and so on. Bottom line, the modified saw will be more reliable. :msp_wink:
can you explain exhaust blowback?
thanks
