That can be possible. If the engine has a leak somewhere the mixture gets to lean, because more air comes in and the engine is getting hotter as normal. That can result in serious engine damage and a scored piston and cylinder. Also a carburetor out of tune (tuned to lean) can cause engine damage. Clogged fuel filters can cause the same or in combination with the other factors. If possible give the saw to a good dealer and mechanic for a check up and maybe if it is worth it, a rebuilt.
Is there a difference between the MS250 and MS250C? Where is the best place to get the parts? Thanks, Bert
