way to check if the vacuum advance is working properly on the Lucas
Dizzy (57 TR3)??

Yes there is a method but it sucks.
Seriously, you can check for a ruptured diaghram by attaching hose to the
port and sucking on it. If you can continue to suck wind, er, air you have
a leak. I have pulled enough vacuum (yeah, I really suck) to affect the
timing on my TR6 once. (I was younger then) But if you want to verify the
advance curve you will need calibrated equipment.
Good luck
