How hard is it to rebuild a vacuum advance for a '36?
Do you have to "peel back" the canister?

Yeh, I saw that before I posted... but I was wondering how hard it would be to do it myself and save the $45.
Today was a "breakthrough" for me. Once I removed the advance from the vacuum line the engine ran really smooth. This is on top of adding a new manifold gasket over the weekend.
Thanks Gene. Worst fear confirmed. :-)

Bill there are two problems with rebuilding the vacuum advance yourself. First is where do you get the new diaphragm? Second uncrimping and recrimping the metal rim.

I guess that I was swayed by the experience when I was working on my Corvette last year. It was absolutely amazing how many different vacuum advances there are available for it. And overwhelming as to how you can choose virtually any range of settings that you want.
So I was thinking that surely someone must have a current Vacuum device that would suffice to replace the '36 one. How difficult can it be? But maybe the low-range that we need is insufficient for any modern reproductions... ?
Dang... I guess that I'm headed off to the post office.

A word of caution on sending off to be rebuilt. There are several types of hook ups onto the vacuum line to the carb. Remove all fittings from the vacuum advance before sending it off. Ask if they will rebuild the one you sent in (not send you an already rebuilt one.) I had one that I got back that the lines did not fit up.
