Query: Piece of junk

If you only need to cut two trees in the whole life of this saw, by all means, buy it. But if you may need to use it more, turn your nose up at it. This is the second one I've had, because I thougt the first one was just a piece. They are mostly plastic, the chain oil tank is just a cavity between the two halves of the plastic body, prone to leak. The engine is ok, but the carbuerator is a cheap chinese made piece of junk (zama brand) that has to be rebuilt or adjusted with a special tool almost every time it is used. The caps for fuel and oil are course plastic threaded so after removing them a couple of times they rag out and need to be removed and put on with a pair of pliers, the magneto is held in with screws that go through plastic so they rag out... Over all a good doorstop, horrible chainsaw.
