The vac retard isn’t connected by the way!

Yes, certainly could be worn out. If you want to take a deep dive into the inner workings of distributors here’s one source:

Sticking or broken springs in the distributor could cause your problem. Finding a source to rebuild your Bosch distributor might be worthwhile. Classic VW distributors are similar so you might find a classic VW place that could help you.
Or replace it entirely with a 123 Distributor. Yours is somewhat unique as I assume you’re running the D-Jet FI distributor but running carbs. Might require a different advance curve with carbs. Don’t know. 123 Distributors can be programmed with many different curves.
Let us know how you make out, and good luck.
