Homelite 330...not too bad a saw, given its price point and the niche Homelite was pursuing at the time.
54cc, about 3.3 cu in, available w/ 16" and 20" bars. same size as Husky 55 for comparison, but heavier and a little less power. Oiler pretty weak, a diaghragm-pump operated from carnkcase pulse. Use light oil and keep the filter clean. reed valve engine, rubber connector from reed block to carb area can crack or slip out of place causing air leak. Best-case if this happens, engine won't run...worst-case, you sieaze it.
Air filter is small, clogs fast most of the time. Easy enough to clean though. They are getting hard to find, and dealers want $12 for them too.
Still has some magnesium housing parts, but they crack easily. Be careful not to let the saw drop on the back handle, as it may break...top cover/handle is hard to get.
I used one pretty hard for a while, even used it to mill lumber. Still have it, it still runs, but it is bone-tired, and not worth rebuilding.
