Thanks again for all the help.

If I pull out the hose for the advance side of my distributer then suck on
the hose the mechanism inside the current distributer moves. If I suck on
the retard hose nothing happens.  With the one I was going to test with I
sucked on the retard hose and the mechanism moved. When I did it to the
advance hose I could hear what sounds to be a broken diaphragm moving about
inside. Hmmm. Probably not worth the check.

I am going to have my current distributers vacuum mechanism rebuilt next
week.

In other exciting events, I finally got a chance to buy some long enough
fuel hose to try Scott's idea to test the noisy fuel pump.  A thunderstorm
has just arrived though....

A couple pulled up to me at a light today and offered to buy my van.
....must....resist....offer...to....end...pain......

Thanks,
