MS 290 spitback

[67L36Driver]

Lots of it. Trigger hand gets wet running without the air filter.

Piston skirt wear?[emoji848]

Other than that, pumps 140 and runs/cuts well. [emoji847]

Hmmm well dont run it without a filter

Rings are mostly gone with 140. Should be near 155 OEM.

Thant's a sign of a worn piston. Too much clearance to the bore.
