Manifold Vacuum Experiment

The second result, "more balls at part throttle", can be attributed to either the full clockwise adjustment (previous diaphram was set to mid travel) or a working diaphragm in the new vacuum adv. or a combination of the two. This second result would have still been realized even if the vac adv. was connected to ported vac. only.

I'm not sure about that. Even when the vacuum canister was good before the swap to manifold vacuum, it did not have what I am talking about at part throttle now. I think it made a difference. Of course all I have is the butt dyno and it is somewhat what subjective. lol
