Cam Timing
I usually put the cam gear at 6 o’clock, and crank gear at 12 o’clock, because it is easier to see if you are a tooth off. Which I think is tdc #6 firing. If you turn the crank 1 turn, the cam gear mark will be at 12 o’clock and #1 firing. This is after degreeing the cam. I degree every one, after finding a couple that were retarded 10* when lining up the marks .
