re: Choozing a sliding compound chop saw

I have a Kobalt 12 duel bevel sliding compound miter saw, which is the Lowes house brand. I haven’t used it much until the past couple of weeks helping a friend retro fit his sundeck. Regardless of the thickness of the piece or the type of wood, the saw burns the the end grain on the right side of the cut really bad, but the left side is smooth. I have put a new blade on it, still the same thing. There is no warp in the wood and the saw is level. It does the same thing if the cut is straight or angled. Of course any joint is very inaccurate. I’m ready to trash it and buy another brand. Any ideas before I do that would be greatly appreciated. Thanks guys!
