You need more initial timing first. I edited my original post to include the vacuum advance. Having it might make the engine run a little better during the times you are under light throttle. If these times are rare, you can run w/o it.

If you are using a vacuum advance connected to manifold (full time) vacuum, this can cause the engine to stall if you don't have enough initial timing. When it goes into gear, the vacuum drops off. This can cause the vacuum advance to drop off as well, and you lose the timing it was supplying.

That's why I said to add initial timing- as much as the engine needs- then to use ported vacuum for the vacuum advance.
