IMHO the time to think about TDC and degrees is when the motor is on the stand. TDC
comes first using a dial indicator. While rotating the crank in running direction bring #1
piston to it's highest travel......file a notch in the pulley that coincides with your fabbed pointer or factory pointer. I'll reiterate what's been said, measure the circumference of the pulley we'll say 6.750 diameter x 3.14 = 21.195 which is the circumference........divide that by 16 ( the equivalent of
22 1/2 degrees ) and you get .755. The .755 is the distance from TDC to scribe/file
your mark for engine degrees. Doing it this way there is not a lot of marks and you'll be so close to perfection you'll buy me a Jameson double on the rocks. Si ?
