Whirlpool has become useless. I posted this over there but the anal mods have gone crazy, deleting sensible posts requesting others' experience/opinion/advice - instead directing you to a canned response basically saying: "Use a search engine." Fools!
Anyway…
I can only seem to find cheap/nasty Chinese tachometers. Which would be fine as long as they're accurate. But I just watched a youtube video where there was 300 rpm difference between two different types. Not a big deal for a lawnmower, but apparently if you lean-out the fuel mixture of a high-revving chainsaw, thinking your rpm is 300 lower than it actually is, you can cook the engine.
I was thinking about a laser type. But most of them have no description of usage, except one that said it requires a reflective strip placed on the rotating engine/shaft. Which kind of defeats the purpose of 'point and shoot'. So I think I'll get the inductive type.
- Does anyone have experience/have one?
- What is a decent (as-in accurate - not necessarily a few hundred $) brand?
- Or to put it another way, where do mower repair places source such tools (rather than the $10 stuff on Aliexpress)?

Yes the phototachs need a bit of reflective tape to work.
