As consumer models go, the 330 was miles ahead of, say, a modern poulan 46 cc job with 20" bar, but not at all in the class of the Homelite 360, with which it was current.
Pulse operated oiler works, barely adequate. Air cleaner barely adequate, and small...must be cleaned often. Cost about $10 for a twin-pack of them. Many metal housing parts, but thin magnesium-alloy cracks easily, especially the clutch cover. No chain brake, if that's important to you. Engine has less total power than most modern saws about same size, but as a reed-valve, is much better at lower rpm. This is good because the 33o certainly won't rev to 12,500. Watch the rubber carb boot...they will crack and leak, possibly ending the saws career.
I have one, and seldom use it anymore. It was responsible for quite a bit of firewood, however. I knock it a lot, because it isn't the quality of a Stihl or Jonsered, but it did work hard for me for a couple of years.
