i was mowing the lawn and mower stopped. i added fuel thinking it was out not sure if it was or not, i went to prime again when the fuel was going in it sounded like the fuel / motor was steaming is that normal?
any way now the mower only runs for 2 seconds and stops
model 944.361543

May be time to rebuild the carburetor.
Very common problem since they came out with ethanol fuel.
Try to find nonethanol fuel or at least add the additive to counter act the effects of it.

ya overthings clear it looked pretty good in there.
fuel looks bubbly tho...
with the carb upside down, is the float be level or slightly up? currently its slightly up

also the air filter cover with the primer bulb, if i blow in the hole air comes out is this normal?

so last week i took apart the carb, cleaned everything. today i went to cut the grass. i cut about 15ft and stopped the mower to pickup some trash and then gave me a hard time to start. i had to prime it alot.
i finally got it running and then would only stay on for like 30seconds and sputter and die out???
