The naysayers clearly do not know that many old cars had worm drive, and did not stop dead as soon as the throttle was lifted.

But if the Andy Crawley is who I think he is, he will be better informed on the works of old motors than many of us.

Cheers, Tim

I am who you suspect I am😉✅.

My main motoring experiences are with chain driven cars however I did once nearly buy a 1925 AC Royal 11.9 which did have a worm final drive. I can confirm that it did not have problems on the over-run.
