Hello:

How long, typically, is a spark plug good for in a typical lawn
mower, and also for a typical weed-wacker, before needing replacement
?

Assume, perhaps, once a week usage during the summer on each.

Thanks,
Bob

pull the plug and check its condition first of the season.
Here is a page that will show you what to look for.

Just change the damn $2 plug once a season or when it's running ****ty.
And spray it with WD-40 -- your wallet I mean. It's squeaks bad.
