A few years ago I helped a friend build some stuff and was cutting 3/4 ply. He had an older Skill Saw (gear drive? the kind with the handle well behind the saw). Anyway it was pretty sweet and I wanted one. I finally brought home a new Skill Saw Mag 77. I think there is something wrong with it. Pushes real hard, even with light stuff and likes to burn a lot. The bottom plate for the guide is very rounded instead of square so I had to go get a new taller 8' guide thinking that was the problem. No difference. The rear of the saw wants to drift to the right. Is there some way I can fix/adjust this thing or should I take it back to Sears? My ancient Craftsman circular saw cuts much better. Thanks........DJ
