Timing lights

Dampeners are 7&1/4 so (1) degree around the circumference is 0.0632683". Measure it out with calipers or a micrometer on a strip of paper & use it to make new marks on the dampener & I'd suggest checking/finding exact TDC first. 35.5 degrees would be 2&1/4" (2.246"). I make new marks using white paint at 10-15-20-35.5 which is plenty & you can gauge with the light when you're halfway between 10 & 15 for instance. Dialbacks are alot of fun to play with but I dont trust their accuracy & reportedly alot of non dialbacks ain't accurate either according to independant studies & reports from many users with more than 1 light at their disposal
