Might have water in the gas.

Just enough time to cut 5 acres.

A dirty filter won't help. Use fresh gasoline. Blow out the gas
lines, clean tank. Check spark plug/gap. Do a cleanup with
kerosene/toothbrush. I'd avoid physical messing with the carburator,
maybe carb cleaner spray will help.

Ideas on what? You have the perfect situation. Wife asks, "Did you
mow the lawn?" and you say, "I did as much as I could. Are you going
to the store? Get some beer. Thanks."

Try primer 2 times, instead of 10. You're likely flooding
the engine badly. Unscrew the spark plug, and pull the rope
a couple times, and then try two pushes on the primer.

I'm remembering a boy I knew years ago. Had one of those
little micro tiny scooters. He primed it about a dozen
times, and when it wouldn't start, would prime it a couple
dozen more times. No matter how much I talked at him, he'd
be pushing and pushing the primer. I finally quit and left
him to his futile efforts.

I push the primer about 10 times, then pull the cord a few
times. Nothing.
When I repeat (it's about 60 degrees here today), the mower
runs strongly for
only 1 or 2 seconds. Then I have to repeat all over again.
It never runs more
than 2 seconds, and seems to run longer with more priming.

I expect it's a clogged fuel supply somehow, even though the
primer does get
fuel to the engine.

It ran out of gas the last time I used it, and now I have
this problem. Maybe
some particles of something got into somewhere. Same gas as
before, not a new
bad batch.

Air filter is not new at all, but I'd guess if it was bad,
then the mower
would never start. (I already took the mower to the basement
to work on it
away from the gnats, and it's partially disassembled - or
else I'd remove the
air filter anyway to see how it runs then.)

Thanks for any ideas.
