Re: [AMC-list] Concord won't start.....

It is possible that the vacuum advance canister, though it leaks, is also
showing that you have too much advance at idle. Source for the canister should
be ported vacuum, not manifold. I have a 304 that had a slight misfire at idle
that was fixed when I changed to ported. That means re-setting the idle speed
screws 'cause the engine will run slower without the advance.
