Since you can at least start the engine, you should be close.  I'd start with around 12-14* BTDC and see how happy it sounds from there. Just remember, if you advance too much you get ping.    Are you using a vacuum advance, or not? That comes into play here too, as you will need to retard the initial advance some if you are useing a vacuum advance.

I agree , start with initial timing in the 14-16* range & total timing around 36* , you will need to disconnect the vacuum advance to do this usually [leave it disconnected]
