Update:

I received my new tach circuit board from Willcox today....I now have a working tachometer.

I did not have a way to bench test it and set it so that I know it's 100% accurate, so what I did was used my timing light that reads RPMs to see if it was at least close.  I tweaked the potentiometer on the new circuit board a little bit, and I think it's now close enough for my purposes.

Did that board end up fixing your issue? I am currently experiencing a similar problem except my tach reads slow/under what the actual RPM's are.
