Vintage Saw Stalker
They don't seem to go so bad that they need replaced, I've had them where they sat so long that the points got dirt or corrosion on the points and they didn't have any fire. A couple of swipes with some fine sandpaper and it was good to go.
They are a pain to work on. Just one of them saws built to throw away after something goes wrong. I did not know that the 330 had points. Thought it was all electronic.
