OK. I did that. It is now timed at 0 degrees, which is actually by the book 
for a 69. The timing light shows 29 degrees of maximum advance with the 
vacuum hose disconnected. Before it was timed at 31 degrees.

I took it for a spin round the block. It seemed OK, maybe with a bit less 
pep than before. I readjusted the idle before I drove it, but I may need to 
raise it again.

I hope I'll be able to take it for a proper drive tomorrow, and then we'll 
see if I still get that noise.
