Found a original New-Old-Stock (NOS) vintage Heathkit automotive engine tester sealed in time! In this video, we unbox it, diagnose why it needed repair right out of the box, perform full circuit calibration, and put it to work on a live engine test.

Before modern OBD2 scanners, tools like this Heathkit dwell/tachometer and tune-up meter were how you dialed in point ignitions, set idle speeds, and tuned classic carburetors.
