Heh, it's like the old engineering joke where the engineer bills the
client $1000 for tightening a screw. The client demans an itemized list
of the charges, which the engineer provides:
Tightening screw: $1
Knowing which screw to tighten: $999
After all, it's only 2 little springs, right? ;)
I did take the Midget up to my parent's place in Upstate New York this
weekend, though. And between the heavier (8 oz) carb springs, re-setting
the mixture, bumping up the idle speed, valve adjustment, and a good
long drive, the car is running quite well. Mileage went up a smidge
(with a hot cam, I don't expect it to be great), and the engine ran
smooth and strong. That flat spot was even almost unnoticeable. Took my
dad out for a spin in the twisty roads around his place and we had a
blast.
I'll keep the Aldon solution in my back pocket, though. :)

You're not going to like this answer...
Chassis dyno is the (easiest) way to go
on this for correct advance curve for
a specific engine.
There is another way to go that will put
you pretty much reasonably in the ballpark, though.
Aldon (England) has about every state
of tune for Series A motors (and I assume
for 1500 also since this uses a Lucas
dizzy as well) ever developed.
They produce the generic "yellow" and
"red" distributors sold by Moss, MiniMania, etc.
