I have to disagree with Jarrid on the points issue - sorry Jarrid. : )
I have seen many cars where the points have gone neglected for many
months. The contact piece between the points and the distributor shaft
wears - especially if there is no grease on them. When this happens, the
car will run properly at certain RPM's and not at others. I have also
seen the screw is under the rotor come loose. This will cause a similar
problem, because the timing is constantly changing. I'm not necessarily
saying that is the case here, but I think it is worth checking out
before you start tearing apart your carbs. In my 18 years of Sunbeam
ownership, I have often suspected the carb as the problem when 95% of
the time it was on the ignition side - and once with a clogged fuel
pipe.

Steve,
I would not suspect the distributor nor its bushings.
When the points go out, you normally get no spark at all.
When the condensor goes ditto.
Sometimes the condensor goes intermittant, so here is
a minor posibility.
As for the bushes, they can limit performance by causing
an erratic spark, but normally this is a continuous thing, not
intermittant, and the amount of scatter in timing is only
a mild performance detriment. The same is true of the timing
chain.
I would look closer at carburettion.
If you have strombergs, suspect that the needle and seat
is in need of replacement.
Also, sometimes the needles stick on the side of the mains
and the venturi piston doesnt move well. temperature often
place a role here due to expansion of the cases.
Also, as the diaphragms age, they first turn hard, which
also makes the piston stick up.
If the pistons stick up, the idle will suffer as well as main running.
I recommend that you remove your air cleaners, and watch the
positions of the pistons. When the car does its thing, pull over,
pop the hood, and have a gander.
If the pistons dont return at idle, you have found the problem.
