Re: She belches!
When the timing is set correctly, the lever should move the timing from 0* to 40* BTDC on the crankshaft. The Model A with a stock head does well with about 30*, so I don't move my lever more than about 3/4 of it's travel. Much or my around town driving is with the lever about 2/3 of it's travel. I have a stock head, but with a high compression head I would use a bit less advance.
