and if it has no rev limiter?
not to be dumb and ask, but is it calibrated for the engine your running? [the little wires on the back]

The tach probably has an issue with the needle touching something inside causing it to drag until it gets past the sticky point.

Does this tach have "Dave Gray" engraved all over it?  If it does I would sure like to meet the guy you bought it from.

Nope its not yours DAVE  sorry it must just be touching alittle caus the more you run it the better it works
