1975 merc 650 s/n 4051811.
Using dial indicator to set timing at .125 BTDC with a flywheel that has no decal. Flywheel had been removed by customer via the 8 bolts. I have determined the 2 degree, 23 degree, 27 degree, and belt aligning mark on the flywheel via small punch marks on the flywheel and figuring what the distance between them should be.
My question is this. what should the timing pointer be pointing at when the dial indicator is reading .125 BTDC?
Thanks
