If anyone has had this problem, this may be a free fix...
I bought a used MS-270-C last several weeks back. Cut like crazy, but seemed to have an intermittent oiling problem. The lcl saw shop suggested that if there was a bad spot in the oiler worm drive, it would probably quit oiling and then NOT start oiling again, and that made sense...so I thought, pondered, cogitated...
Although never a pro, I have cut heavy-recreationally for the past 40 years. Always when flipping the bar or adjusting chain-tension, I have put upward-tension on the tip of the bar while re-tightening it to the power-head. However, my "new" saw has a "quick-adjust" chain tensioner. When I looked carefully at the operating manual, they mention upward pressure on the bar-tip while tightening the NON-QUICK-ADJUST model, but they do NOT mention it for my model -- (they don't say not to pull the tip up, they just don't talk about it). So, while adjusting the chain, I tried letting the bar seek its own level while re-tightening: 'Problem seems to be cured.
BTW, I bought the saw to replace an old .025 for bucking/blocking. It is heavier, but you spend less time per cut. I really like the saw. Pretty nifty.
