"Stumbling"
Got back out for another test drive - same thing.
Then I remembered that I had a similar thing occur with my '53 R-110 and it was the coil going bad. I had a new coil I was going to install anyway, so wired it in and took another test drive - same thing.
So it would seem it is either a fuel delivery issue (haven't checked the fuel pump and fuel flow yet - flow should be 1 pint per minute and pressure between 2 and 3.5 PSI) or an ignition/timing issue related to the distributor. Without completely taking the distributor apart, I checked the points gap and set at 0.020" (specified range is 0.018" to 0.024"). Still stumbling.
It is my understanding that the vacuum advance only comes into play at idle and very low RPMs and the mechanical advance regulates timing for higher RPMs. I would have to tear the distributor apart to get at the weights for the mechanical advance - point plate held in by 4 bolts at 90 degree increments around the distributor, which is a Delco-Remy 622R.
Am I headed in the right direction on this or am I not considering something else that I should? Trying to tackle from simple to more complex, so before I take the distributor out to investigate further, I thought I'd check in here.
Don't give this old shade-tree mechanic too much guff if I've missed something obvious! LOL
