Re: Adding Hour meter
The hour meter/tach combination is available from aliexpress also. I have purchased five, I think. They have resettable 'service' intervals, show the rpm when running, and display the total hours/tenths when off. It will take a week or two for them to show up, perhaps longer. Cost about $6-8, to your mailbox.
They come with a pair of zip ties and an instruction sheet. Battery is expected to last several years. There are models that have replaceable batteries at higher cost.
The tach function is settable for number of cylinders/2T/4T, etc.
The wire that is wrapped around the spark plug is over a meter in length. I thought about running the wire through the central beam of the Snapper, but have decided I would not want it by the controls as there's no good place(IMO). I think I'll put it back by the engine, perhaps on the cooling shroud, using two-sided tape. I don't need to watch the tach when mowing, though it might be interesting for a minute or two.
I would suggest using tape or bread-tie wires to secure the meter wire to the sparkplug wire.
simplificate & add lightness
It's not how hard you work, it's how much you get done.
