Well, I know that the 1127 saws have compensating carbs in them. I also have owned over a dozen of them (290 and 310), and they run just fine with somewhat dirty air filters. The AFs are larger on these 290 55cc saws, as compared to the really small ones on the 50cc 260 saws. From the photo above I do not see a dirty air filter. I see a flocked AF that has some color to it. Yet people on this thread have gone completely overboard on the carb and choked up AF issue, and on various ways that the thing can run lean (in my experience they run rich with either clogged AFs or muffler screens) but that is not the problem with this saw. There was no lean seize or signs of any overheating on this saw and that piston and ring set is down right 'perty. No transfer, no scoring, not even any streaking, which are the typical signs of running lean. So it is far far more likely something else. With the bar code sticker still looking like that on the front of the saw, this saw has really really low hours on it as well. Barely broken in. Likely a factory defect or failed part cause this seize.
