If the teeth are excessively worn or broken and/or the bushings are worn out that can cause the symptoms you mention. This has been a serious flaw in the newer version of that saw, from about 5 years ago up to and including the ones they have now, and if the gears are excessively worn and/or have broken teeth it very well may not be practical to repair. The worm gear and shaft bushings however are an easy repair if that is the biggest problem, if they are worn the worm gear will slide slightly and the gears will not mesh properly causing that skip you described..
Kind of a coincidence this has come up because I have been meaning to mention this very problem since I have recommended the HF saw several times here in the past, but no more! FWIW, the Clarke brand saw at Northern Tool appears to be identical to the old saws from HF and they are priced about the same, they may be the same saw but I can only say they look to be the same. In any case I have to do a 180 on the HF saw and take back everything good I said about them, the saw they sell now is not the same saw they had 10 years ago when I bought mine.
Thanks for the advice. I also noticed the guy I bought it from didn't have the belt tight. He had it set set so he could switch speeds with little or no effort.
After I get the gears cleaned up, I am hoping that between the belt not being tight and the sticky glue type grease, that it will work like it is suppose to. This machine doesn't look like it has many hours on it at all.
Maybe the grease set up because it had been setting without being used for so long.
Thanks for the advice.
