How to tell 168 tooth flywheel from 139 tooth without counting all the teeth. This is a 168. [img]https://www.stovebolt.com/ubbthread...oad/Number/49654/filename/clipboard1.jpg[/img]

Distance between the 1st and 10th tooth is 2.363". 6volt distance is 2.86 inches.

Before someone asks which tooth is the 1st tooth, any tooth can be the 1st tooth, then count 2, 3, 4 etc. until you get to 10.
