View Full Version : Ignition: Interpreting timing mark

Have a crank wheel with a yellow stripe painted for timing. Looks factory. Pointer is set on bottom of yellow stripe during timing check. Should it be in the middle, top or bottom? Thanks!

What engine are you working on as the timing marks aren't the same for all of the Studebaker engines? Bud

If the "mark" is on the "IGN" fine LINE to the Right of the UDC (0) Mark, that is where the pointer should be, ON the Line that would be 4 Degrees factory setting but it may run better advanced more with current Fuel, like 6 or 8 degrees you have to guess at that as there are no other marks unless you use a "Setback" adjustable Timing Light.

is advance toward the UDC(0) mark or toward the IN-OP line.

Advance would be away from the UDC,
