<p>I got a chance to tear into a 280 today. Glens is right, it's a cross between a 290 and a 360. The cylinder is much more like a 290, but has a magnesium bottom end instead of the engine cap. This thing is cheap though, like Bwalker mentioned, for assembly line production. The exhaust port is oval. The muffler has a matching oval flange which sits in the end of the exhaust port, just like Stihl weedeater engines. The ignition module is the same as Stihl's weedeater engines. The carb is a tuned-down Walbro HD. There's a spit-back piece which bolts over the carb and you'll have to cut it for more breathing power. The cylinder has finger ports and a steeply-angled intake port. In short, it's a cheap, consumer grade saw with a few good features. NO adjustable oiler. Spur sprocket from the factory. Plastic handlebar. Slab-sided piston which looks poorly cast. In short, save yourself a headache and buy a 260. Not the 260 pro, because you don't need a compression release. The 280 is a cheaply made, consumer grade saw. It's also going to be a high maintenance unit. Those weedeater-style ignitions don't last long. We have a lot of failures already on the FS-85 and the new "EZ-to-start" FS-55.<p/>
<p>If you need more power than a 260, buy a 440. It's almost the same weight as the 360 and the 440 has better porting and a stronger engine.<p/>
