Adam:
Sounds like something is loose or worn in the distributor.
Check your points and the mounting plate for looseness, make sure the
shaft does not wobble. Something is wrong somewhere....
Also check your vacuum retard capsule for a leak. You should
be able to pull a vacuum on it, and it should hold the vacuum for
10-15 seconds no problem. If it is leaking, replace it. The diaphragm
dries out and cracks over the years, so it is a wear item.

Subject: Engine... distributor
All,
I found my problem. actually two. One of my sparkplugs decided to not
work
much anymore, thus I was running on 5 cylinders part of the time.
Apparently it worked sometimes but not others. So, I replaced the plug
and
gave her a test drive. not much power and still missing but not as bad.
I
checked the timing and found it was way advanced from where it was
originally set (I had timing it statically and dynamically verified). I
adjusted the timing again dynamically to 4 ATDC and she ran smooth with
good
power. SWEET! However while I was driving I noticed when I stopped at a
stop sign that my idle had increased to 1,000 RPM from around 850. when
I
got back to my garage I checked the timing and it had again advanced
itself
some (but not as far). I reset the timing and reved the engine a few
times,
checked the timing. again it was advanced from 4 ATDC. Is this normal?
I
verified my vacuum line is working as when I pull the line the RPM
jumps.
Also, where is a good place to get distributor parts? I'm looking for a
clamping plate for a 73 distributor in particular (the one on my car is
pretty messed up from the DPO). Also, is there a cheaper place to find
new
distributors (or refurbished/rebuilt) than TRF? (mostly looking for
cheaper!!!) My $5,000 car is rapidly approaching $10,000!!! :-)
Thanks!
Adam
