G12 Coil Ignition timing

Post by GSM »

I have a 1960 coil ignition G12 with the 18D2 Distributor.

What is the best way to check the static timing, and what should the static timing be? The manual only shows how to check on a single. I have a timing disc.

Also, is it worth checking with a strobe light? If so what is the best way to do this? What should the maximum advance be and at what RPM?

Page 42 in the 1960 manual.

Dave, I saw that, but it doesn't say how many degrees BTC for static and doesn't mention what to do with the distributor auto advance.

It does, it says turn the rotor clockwise to fully advance then set as for magneto twins. On page 42 for the Magneto twins it tells you to set it to 11/32" BTDC, further down the page it says 11/32" = 35degrees.
