M@W dyno parts

Anyone know

where I could get a tach for a P400 or someone that could repair my tach? It spins but there’s a spring broke inside.

Link is a long shot from 10 years ago. Looks like Sept. 2016 is the last time Pete posted on YT if that means anything.

Awesome looking gauge , interesting.
If it’s a spring is broke ,then suggest depending on the type of spring. Try to start , McMaster Carr with its type and dimensions for commons types .
If special I go to Spring Team in Austinburg ,Ohio . There staff has been extremely helpful to me for solutions to my spring question.
