Measure the circumference of the balancer and divide by ten; cut a piece of masking tape that long (which is 36*) and place it on the balancer, clockwise with the end butted against the timing index line. When the bottom (most clockwise) end of the tape aligns with the “0” mark on the timing tab, you’re at 36* BTDC. divide by 36 that gives 10 degs.
