Locating dimple on timing gear

[katy]

One easy way is to check/set the points gap before putting the distributor in the motor, put dist. in the motor, fully retard the spark, set timing pin cylinder 1 TDC, and then use the Nurex Timing Wrench. It may not be 100 % fussy/correct, but is real close and is a quick check. The Nurex is especially useful for side of the road.

Eyeball works real good, been using that method for over 60 years.
