[66Submarine]

Tuning tip. I'm certainly not claiming to have made this up, but it seems many people overlook the idea. Timing tab only goes to 16º BTDC and you want to check total timing without a dial-back light? No need to buy anything, just divide the circumference of the damper by 10 and make a mark on the damper that distance from the original mark (360º/10 obviously=36º). Mark the distance on a piece of paper or masking tape and use that to transfer it to the damper. Want 32º total? Just line the new mark up with the 4º ATDC on the tab. Quick and easy.
