Manifold Vacuum Advance what am I not getting?

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.

I get it. 42° is way out of wack from what you guys consider normal or acceptable. I have no feel for this. But I hear you loud and clear and it is probably where Rusty was coming from as well.
