Response to I have been using manifold vacuum

I wouldn't change too many things at once

The Mallory distributor uses a measurement tool and you can set total by adjusting a stop plate, it's very easy.

And yes, you measure total with a light by slowly revving the engine until you are sure it stops advancing. If it is a stock Unilite, it is likely going to advance until about 3000 rpm, but go a little higher than where you see it stop so you are sure.

So the 2 degrees, should help, setting total should keep you safe, idle it as low as you can and have the carb adjusted right, then get a few miles on it.

Unhooked advance won't help you at this point
