Jan, thank you for the detailed information. I filed the contact points 
in the relay and, viola!, no more stopping in mid stroke. All is well.

Never did figure out how to get the cover off  to grease the cam 
mechanism, but that will be a project for another day.

Many thanks to you and others who responded.
