John,
Thanks for all the info.
The springs in the distributor have approximately 7.5 turns and are 0.820" overall. The diameter of the spring is 0.185 and the wire diameter 0.038" so actually fairly similar to yours apart from the smaller number of turns which would presumably increase the spring rate.
Whilst the distributor was open I tried prizing the weights apart and the cam definitely moves OK but trying to open the weights by rotating the cam is extremely difficult.
I now have to admit to a schoolboy error in that I hadn't thought about the camshaft running at 1/2 engine speed meaning my timing marks were just under 0.6" apart so no wonder I didn't get the full advance I was expecting!
Anyway, I have now played around with the static setting and the car is definitely running better although still not perfectly.
John.
