Vacuum advance not working properly?

Running manifold vacuum to cure way to much cam in your motor (AKA poor planning) will work but with that much cam the vacuum levels will be lower than in a normal engine and there will be no mileage increase. Otherwise the cam belongs on a race track not on the street.
I'm not arguing-just stating the sequenc on should take.
The gentelman we are trying to help may very well be better off running ported vacuum.
I feel like we've both made good points for him to try.

It's all a guess from where -we- are sitting. :/
MP, are you new to website-forums and/or newsgroups by any chance?
If so (sounds like it to me) you can see this is a whole different world than the "real" one, huh?
It's as if each and every one of us is getting our words and wording scrutinized like GWB himself.
With your experience you have a lot to offer, the trick is to -add to- the common knowledge here (we'll all learn something and you too) and remember, on website forums only the moderator gets to have the final word on anything.
Newsgroups that way, are even worse... no one gets the final word there.
Being a libertarian I kinda like it that way, but I'm really weird. :/

This thread's tally is 31 posts and 319 veiws.
"it's all about the thread"
If a guy posts something that's 100% "wrong". and it prompts a lurker or anyone to explain why in detail. The thread is a success. Neither post is more worthwhile than the other.
I never had numbers to back it up before but I always figured only about 10% were actually participating in any particular thread. (I'm new to website forums)
It's not the post or poster that's the most important IMO it's the tread and its combined information and rebutted mis-information that counts. With a 90% lurker count even the OP's (original poster) question can become secondary in a really good thread. Heck he may have asked the wrong question even. And he finds that out in a good thread.
----------------
After getting a Comp-Economy Cam in my 360/2100/DuraSpark, I had a little trouble with the engine advancing its own timing and so speeding up its own idle speed. I didn't drill holes in the throttle plate but I'm figuring on trying something like that some day.
The distributor port vacuum can get effected and away it goes.
It's a symtom of another problem, it seems to me, of the carb idling using at least some of the low-speed-circuit instead of solely the idle circuit, for idling.

ps- There I made statments. You think I'm wrong or only half right, state your case for it, I'll agree with you or re-build my case, by the end of the thread we'll all be smarter?
