A stuck mech adv is a common problem, usually because no one 
has lubricated the felt plug in a couple of decades. Disassembly is 
easy if you know the "trick." Just grab the cam in soft jaws of a 
vice, remove the felt plug, and tap the center shaft with a punch. 
This takes about 30 sec. This doesn't hurt anything because the 
back side of the snap ring retaining groove is sloped.

I assume it was the 2 halves of the breaker place which were stuck 
together. Make sure to lubricate all the sliding surfaces with grease 
when you reassemble. I usually work over the sliding surfaces with 
a whet stone if there are burrs. You also need to check for wear 
and that the copper braid is still good between the two plates.     

Replacement plate assemblies are still available, but are seldom 
needed if you take care of yours. I have seen ones with the center 
hole of the lower plate worn quite oval, however. These are shot.

It's actually felt, but it looks like leather where it has touched 
against the cam for decades. Put a few drops of oil on it. The cam 
itself, like the ignition cam should get a light coat of cam grease.

A drop of oil here, yes!   

Yes, a non-functioning mech adv will make a car almost pointless 
to drive. I fix a lot of these. Whenever I open up a dist with mech 
adv the first thing I do is grab the rotor and turn it. It should turn 
easily up to its stop and then return under its own spring action 
when you let it go.

Sorry! I don't have any.
