Ron,
Is this some kind of a special project you are working on, or do you
just want to get your lawnmower running? If it's a case of just
getting a mower running - provide some specifics like engine name,
numbers, etc., and either I or someone else can probably help you out.
Ken.
I was working on my father-in-law's lawnmower. I replaced the points
and didn't want to do it every year.
I recalled this simple little circuit and got obsessed with finding it
again. Still no luck.
The zener and SCR sounds like it may be the ticket.
Thanks everyone for your responses.
In all my years of mowing with junk mowers, I have never replaced
points; touched them up on the grinder a couple times, freed up the
plunger occasionally and replaced the plug once or twice. Most I ever
paid for a mower was $15.00 but that one lasted 22 years mowing a
minimum of three lawns full time.
