1. No, you don''t have to pull on it, it just rotates. There is an
internal spring, so there is some resistance.
2. Yes, you can hit an end point in either direction. I *think* I recall
that the entire range of adjustment is less than 10 degrees. If you run
up against the end point you will have to rotate the distributor itself
to get the timing where you want it.
3. To rotate the distributor you loosen the clamp bolt on the collar
which is bolted to the block (see your manual). Be very careful when
retightening this bolt! The part of the distributor housing where it
clamps is merely a thin pot-metal shell, and is easily crushed. The clamp
can act as a pair of shears, especially if it is not on perfectly
straight. This is probably the single most common cause for distributor
replacement.
4. A hint: when you have the clamp bolt loose, first get the Vernier in
the center of its range of motion, then adjust the timing by rotating the
distributor. This will set you up for next time, so that you will be able
to use the Vernier for up to 5 degrees adjustment A or R from where you
are now.
Good luck.
