Manifold Vacuum Advance what am I not getting?

You’re saying do not tune for Max vacuum? I can certainly take the initial down to 24° but my vacuum will be at 10Hg. The problem with the idle speed is that there’s a significant drop when it goes into gear.

Right, but jamming another 18 or 20 degrees of initial isn’t the fix.

You can’t fix a fucked converter with a timing light.

All you will do is kill more parts.

I wish you were closer and I wasn’t so busy.

I’d put your engine on my dyno and sort it out.

What you are doing is trying to fix a hard part issue with tuning.

That’s not a good plan.
