jharvat -- Great to hear you're pleased with the results of AD. Can you please let me know how much they charged for the rebuild service as well as the turn-around time? Thanks.

For my particular distributor, they charged $200. But they returned to me a little jewel - it makes the rest of the car look bad. Turnaround time was about 2 weeks from my mailing it to them to me getting it back in the mail - so pretty quick considering the quality of work done.

Gary - thanks for the advice on the ground wire. As you say, it couldn't hurt to ground it.

OK, now back to my usual dumb questions. Where exactly did the vacuum control hose originally run - from the distributor to... where? My thought is that it probably attached to the stock intake manifold someplace, but I've got a triple Weber setup on the car so I need an alternative spot to make the connection (short of running the hose all the way to the rear section of the intake manifold, which is where the previous owner had put it). Any ideas?

Connect to behind the front SU carb.

Triple Webers don't have a ported vacuum source, that's a hose to nowhere.

You could try using the vac advance referenced to manifold vacuum but don't expect the results to be great. You'll likely end up with static timing too retarded, thus limiting WOT performance. FWIW, tailoring a spark-advance curve to an engine is not trivial.

According to http:

triple Webers run better when you do not use the vaccum advance. This is probably why yours was not connected.

Don't quote that site, there are tons of misconceptions in there, especially the Weber section.

DJ, turns out you are correct. Advanced Distributor also recommended that I not hook-up the vacuum advance with the triple Webers. So, I will just leave well enough alone.
