Another timing question

[The Drach Man]

Hi all. Never seen this before, on a 1973 Electraglide. Which one is the advance mark? Dots, or line? I interprete the 'T:F' as 'TDC: Front'.....I've gone with the dots, a. Because front cylinder is on compression stroke, b. Because I can adjust point gap on the cusp of the ignition cam. With the line, I can't get near the cusp....advice please

You could try using a measuring stick and set the motor to 7/16" BTDC on the front cylinder compression stroke and see which, if any, of the marks line up.

Not sure they are even factory marks? (will look up when get home)

Could it have a aftermarket crank? Never seen those in the service manual.

I think Hodgie has it... S&S Flywheel timing marks.

If you keep spinning, you'll see numbers identifying the wheels spec if S&S.
