Started working on 51 3104 this weekend, hasn't been started for over a year. After the usual shot of seafoam and motor oil in the cylinders in case of stuck rings, cranking with plugs out, etc. etc. I was ready to start her up. My almost 5 Grandson patted her fender and said "come on old baby, fire up". When I was done laughing I put the key in and it wouldn't turn. Trip to NAPA for new switch, came back and read service manual to figure out how to remove the old one. When I pulled the cylinder out inspiration struck! Maybe I can save it. So I cleaned it up and put it back together, it worked and the "old baby" fired up eventually. But the switch is stiff and I'm thinking about pulling it back out and lubing it. White grease, lock ease, never seize, muffler bearing grease. Any suggestions? Thanks.John
