So on my MS362 Stihl.. I cut up a bunch of big logs a couple weeks ago, saw worked great. Then the last couple cuts were labored and I just figured the chain was getting dull, even got some smoking out of it. (the chain not the saw itself). Took it back to the shop and sharpened it.. no change, labored to cut and a smoking bar AND it was cutting in an arc. Dressed the bar so the rails were even, cleaned everything up, made sure the oiler was working. Put it back together and same thing, seems to cut crooked, smokes , and labors to cut!!
IDEAS???
