He is going to call me on Monday so I can run up and get them.I dont hear a thumping just what sounds like bearing noise but that has begun to fade to about 1/2 of what it was when I firt plugged it in. I cant read the silkscreen good but when I switch the knob from what appears to be 8 lobe to the left 2 positions the tach steadys. I will figure something out for square stock next. I have the battery on a charger now and will run it again this weekend to see if I can get the dwell meter working
