(1981.9L) Got the tin off the bottom of the left head. Three 13mm and
one 12mm? Who designs such things?

The switch reads open to frame with the engine off, so it's a goner.
Found the fossilized remains of what appears to be an ancient
Pre-Columbian rubber boot on the switch. After than crumbled off, the
the brass push-on connectors had nice green verdigris.

I gotta do something about this.

When I pull the switch, will there be much engine oil loss?
