I have a Mallory Model AY, type 11A distrbutor which has a centrifiugal advance no vac or manual advance.
It does not advance far enough. Does anyone have instructions on this model or know of anyine who can service it?

I am sure if you take the top plate off there is a mechanical stop for the advance that can be bent to adjust it.

I have a a Mallory on our Model A, not sure which model it is, but it came from Bubba.
There is an adjustable plate in it to limit the advance. In our case, with a 7:1 head, I've had to limit the maximum advance to 28 degrees, but just very occasionally when charging up a hill at high revs in top gear (probably 3000rpm) Before dropping it into overdrive, it just starts to pink. Otherwise never.

Increase the base timing to compensate, provided everything else is good.
