Ex, I'm also not sure what Jimmymac is trying to say...earlier in the thread he said this:

Do you really believe there's a vacume advance distributor out there? Are you aware of the full meaning?

then this:

Try pulling the vac line off the from the carb. Hook up your timing light. start it.check timing. put a vac on dist, check timing again!!!

then this:

So diddn't put the old vacume advance dist to the test did ya Ex. Some buy em some build em, Some just talk.

I think he thinks a vacuum distributor doesn't advance the timing when it receives a vacuum signal? Jimmy, it doesn't wound like you know what you're talking about. I have done exactly what you described, and the timing DOES advance when you add vacuum to the can...what are you trying to say? I'm sure Ernie has done the same thing, and he's probably forgotten more than you know about motors...tell us clearly what you think happens when a distributor with a vacuum advance can operates normally.
