Here’s what I did today. Took the belt off and fired it up. The motor ran smooth. Put the belt back on and removed the blade and there was a slight vibration but it is livable. Now I’m saying to myself, What the hey. I put the blade back on and the motor jumps all over the place. OK, I got a bent blade. Nope the blade is flat and true. I use the Freud blades and this is about the 10th one I have had on this saw in the past 5 years and I have always had this problem. So, I tried another blade of a different make, same problem. I put a full kerf blade on it that I check for flatness and the motor still jumps. The saw is the Delta 36-979 with the single pully on the arbo rand the nut is tight. I’m really at a lose here.
