Rookie Questions about Timing

I've got a '71 CB350 K3 that won't start. I suspect it's the timing so I'm trying to get that set correctly. This is my first time to adjust the timing, and I have some rookie questions.

1. What is the purpose of the felt underneath the main cam? Should it be making contact with the cam? Mine's not. Is that a big problem?

2. My Clymer manual says that I should apply a light coat of breaker cam lubricant to the entire points area when I'm done. However, I can't find that stuff anywhere. (Apparently most of the folks shopping at AutoZone these days don't drive vehicles with breaker points. :D ) Should I use some other lubricant? WD-40 perhaps?

3. And this is the big question... Instead of using a test light, I'm trying to use my fancy-pants multimeter to know exactly when the points open. This has been an interesting experience and has already provided me with a much greater insight into how the ignition circuit works. (Most importantly: it works exactly opposite of how I assumed it worked)

The Ohm meter function of the multimeter has a buzzer function... as long as the circuit is complete, it will make a beeping sound. I adjusted the points plate so that the beeping stopped (i.e. the breaker points opened) right when the "LF" mark passed the index mark.

To double-check my handy work, I turned on the ignition and switched the multimeter over to read the voltage. This, however, yielded slightly different results. The voltage level starts rising a little bit before the "LF" mark arrives at the index mark.

Is that normal? Should I use the Ohm meter results or the voltage meter results?

As always, I appreciate any insight you guys can provide to a rookie!

Yep, just reposition the felt block so it touches / drags on the cam.

I've just used a few drops of whatever ol' motor oil happened to be in the oil can at the time... :D

I mean, you just want to keep it from drying out. Otherwise, y'get dry surface rubbing on dry surface, and y'get accelerated wear on the little points opener nubbin and more frequently having to reset the points gap.

But not so much slopping around that the oil fouls the points surfaces themselves.
