I am interested in documenting some baseline tach readings for my postwar engines. Toward that end I would like to purchase a reliable tachometer for measuring small motor RPMs.
A search of the forums came up with hits that refer to built in tach function in newer engines, no standalone devices that could be used on older engines. Perusing through Amazon it seems many of the "touchless" tachometers rely on reflective tape. Anyone here have any experience with this, or a favored/recommended tachometer?
