Mallory Ignition

[Bob Grieb]

I recently purchased my second Model A (1928 Tudor) that has a Mallory ignition installed. It has a dual point system and seems to run quite well. The problem for me is I have no information on how to set timing or point gaps. Can someone point me in a direction that will lead to an understanding of the ignition system. I plan to pull the head this weekend and want to make sure I can properly set the ignition during reassembly.

Thanks for you help.
