vaccum advance question

[76bonanza]

I have an advance problem.

First I have a leak in the rear of my canister I can stick my finger back there and it sucks it up to a little hole in the rear. I am guessing that is not good?

I get no advance at idle if I hook it up to full vaccum I am guessing that is not good either.

So is my advance bad? I have an accell distrubuter can I just replace the advance and is it easy? Also If I drive it for a while like it is will it hurt the motor?

Thanks for all your help.

and plug off that vac port untill you can replace the unit.

Got it off no sweat going to get a new one. Should I replace the rotor also? I have an accell super coil cap and coil And looks like an MSD modual(yipee)

If your cap and rotor looks old or questionable, replace it whiel you have it off. Puttin a bad part back on is kinda like taking a shower and putting on dirty underwear.

Ok good to go replaced it all better now thanks.

One more thing I am running full vacuum to my advance.

What is the exact process for setting idle mix when you are using manifold vacuum for advance(please no arguaing about which port is best.
