[Shotimes] clutch switch

[van Oss]

My 91 (129K) misbehaves when starting on cold mornings.  If I press the clutch pedal for 2-3 seconds before starting, then the
starter engages nicely, although not perfectly smoothly.  If I go too fast, starting is a bit erratic, as if something is not
engaging.

I suspect that the clutch switch may have a little arthritis and is not moving quickly.  What would be a good lubricant for this
switch?

Another possibility is the starter relay, which I believe is original.

How about the starter solenoid?  Although the relay is on the fender wall, the solenoid still is inside the motor housing, isn't
that right?  Might I be looking at a starter rebuild?  If so I'd rather do it now than a week or two hence when the weather gets
nasty.  (George and Alan, use your imaginations.)

Advice please, Obi-Wan!
