I've got a MS880 here for mods. The first order of business was getting rid of the rev-limited coil and carb. The coil was replaced with a new one for a 088. The carb was replaced with one off a 084, ultrasonically cleaned, and a kit installed. The only other mods so far was to the muffler. I simply extended the factory deflector and enlarged the exit hole several times larger than it was. Even with the spark arrestor screen replaced, it's still probably flowing as much as the deflector will allow. I've got the saw tuned to 13,000 here. The chain could use a touchup, but you can still see how the saw's running. It's wearing a 36" .404 full-comp RSC chain.
EDIT: IT IS NOT NECESSARY TO REPLACE THE CARB ON THIS GENERATION OF 880.
