Thanks Al that is the first thing I would do also chuck that sucker.
Willie, on the older 020s, and 020Ts, the settings are 1 1/4 on each screw.
The MS200 and the MS200T the settings are L- 1 and H-3/4 turns.
From what I found there are 8 different carbs that have been used on these saws. Good luck and let us know what you find.
