Setting vacuum advance

Yes, you can. I have done it so many times, I have lost count. The AK moves a plate that compresses or un-compresses a spring to change the rate.
You are the one providing misinformation.
:rofl:

You're hilarious!
Spring rate is not the same as spring force.
You need to review your high school physics.

Considering you've never seen the inside of a Chrysler distributor until looking at the photos people posted here, you have a lot of gall to claim I'm providing misinformation.
Everyone one of those photos I posted are distributors I've taken apart. I've run quite a few on a distributor machine and quite a few measured on an engine.
You argue about how a vacuum advance works with Halifaxhops who has run hundreds of distributors and done concours restorations on many.
I've told you several times that Chrysler vacuum pods are not the same design as GM or Crane, but you're the expert. OK
