Turns out one of the springs is missing off the advance mechanism. Not sure where it went as it wasn't inside. In the meantime I've gone for a Megajolt set-up and ditched the distributor.

I assume the noise was detonation as it was advancing too quick.

Anyone got a Map for a 1776, W100 cam, standard heads, 40DRLA's in a lightweight car?

When I wiggle the distributor drive shaft there is more back lash on the noisy engine than on my spare one which makes me think the brass gear is damaged.
If I can get the distributor drive shaft out am I likely to be able to see any damage to the brass gear?
OK, I'm confused. If the same problem exists with different distributors, how do you conclude that a "missing" spring in one is the issue?
The 0 231 178 009 distributor has a place for a second spring, but none is fitted from the factory.
As I stated earlier, a 40° curve is a rarity - 009s typically have around 22°.

Didn't know that. I saw the space for a spring and assumed it was missing. Mystery solved if it wasn't there in the first place.

Don't let that stop you from switching to a fully programmable ignition if it is in the budget.

The MJ+EDIS setup does away with ~everything that can go wrong with a stock T1 ignition, and they are relatively bulletproof OEM automotive grade hardware for all the critical bits.

...but I still have serious doubts about your timing light.

Most auto parts stores will loan you a good one, for free even if they help you with the test in the parking lot.
Addendum to Newtons first law:
zero vehicles on jackstands, square gets a fresh 090 and 1911, cabby gets a blower.
EZ3.6 Vanagon after that.(mounted, needs everything finished) then Creamsicle.

Megajolt now installed and the timing is rock steady exactly where I set it and advances as it should. And the noise has gone. I couldn't see any damage on the driven gear so maybe it was the drive gear but I don't care now. Looks like this.
