How to - Hillbilly Timing Tape
@4spdragtop
Part of the reason I only do two marks is you don't have to figure out which one is which if you place 6-8 marks on the balancer. If you where to make the marks different lengths, all across for 10* levels and half for 5* to differentiate, that would be good.
The only time math comes into play is when you are actually timing the engine. the 15 mark will allow for timing from 5-25, the 30 mark from 20-40.
