So far I have had 3 of the motors start fairly easily after sitting for many years and they seem to run fine and I switch them off but I can't get them restarted for some reason, even with a puff of starter fluid in the plug hole they won't give the slightest hint of a bang or flutter. I have had a couple of PT do this as well recently, no idea what is going on with them when they react in this manner. The one I had that was kicking back, I tightened the belt a bit more and that seemed to help. Still not starting as easily as it should, takes at least 3 pulls.
