That's clear -- I was just thinking I might catch it acting up, thump the
carburetor, and if it jumps back into normal operation I'd have good reason
to suspect the valve was sticking.

I put in a new condenser this evening but noticed no change in performance.
It idled fine for about 10 minutes, then I took it out on the road and lo
and behold! it started the hesitation, throttle mushy, stalling, then dead
act again.

I nursed it back home and decided to risk the "Alan Bowes patented
burn-your-place-down test" -- I checked the fuel pump by pulling the outlet
side loose and watching the squirt action while cranking the engine.
Interestingly, it took about a minute of cranking before I saw any fuel (of
course, it had just been exhibiting the symptoms) then when fuel finally
arrived, the pulses of fuel were few and sometimes far between. There were a
couple good blasts that shot out 3 feet, but for the most part, it was
miserable. It was really sad to see it go 10 or 15 seconds without a squirt
at all.

I think I've found my problem.
