700 Flywheel Timing Decal (3 cyl.)

[dtmc78]

I have a '78 Merc 700, 3CYL. Most of the timing decal is warn off but I do have a few marks visable. Does any one have this model that can give me exact measurements between marks. I have; ".464 BTDC" and the first mark for max spark. After that point it fades into nothing (Don't even have TDC).

Thanx in advance,
Dave
