For years my stock G10 has had a spot just above idle that is non-linear; results in jerky acceleration when driving slowly. I have fiddled with various things (it has been a while) without luck. I don't think anything is broken, car runs great. Any ideas?

Did you check the TPS? An analog meter will be better, as it's more "graphic"; when looking for flat-spots (inconsistencies) in the resistance-readings.
A vacuum leak or fuel problem could also cause a jerky acceleration.

When I bought my cultus I had a flat spot under initial acceleration and upward gear changes. Turned out the two hoses on the vacuum advance unit were mixed up. Or as said above, you may have a vacuum leak. There's a good fww vacuum lines on and around your carburetor and they will wear over the years.

I just had the same problem and changed the tps and it's running great now.
