Fixed the armature plate wiggle as per Joe Reeves instructions. Motor runs like a charm now. Before in the test tank could only get 3000 +- rpm. Now I can get over 5000. I let off when I hit 5000 in the tank.<br /><br />Question now is what is the rpm operating range for this motor? It is a 1974 25 hp Johnson.<br /><br />Thanks to Paul Moir for directing me to Joe's fix. Saved me considerable time and dollars.
