David:
As a digest lurker, I don't know how much response you get in real time.
My 2 cents worth is to check the rubber diaphram for the throttle slide
inside the carb. It gets old, brittle, and eventually tears. Then the
symptoms are as you describe.
Don't know anything about Jettas.

Subject: Spitfire Temper Tantrum?
I had a problem at the end of last year with my Spitfire which,
strangely, is similar to a problem I've had with my 87 Jetta.
At about 2000 rpm, she threw a little temper tantrum- some roughness
came on which matched a problem I'm trying to diagnose with my other
car.
The roughness makes it so that the car will not run over about 2100 rpm-
it just jerks right at 2100, no matter how high I try to rev it, until I
decelerate. Very frightening. The tach jumps between 0 & the actual
reading, and as soon as aI get off the gas (and bre\ing it below 2100),
it runs fine. The problem persists, at the same rpm point, when I try
to rev it in neutral- ie, it does not depend upon the load on the
engine.
