lawn mower keeps dying Answered

bought a new 2 cycle lawn mower in the spring. It worked fine, then it starting dying. I unscrewed the gas cap screwed it back on. It worked fine for a few turns. Died again. Figured cap needed to be vented. Now it dies continuously. Need some suggestions.


Ring or email the mover wreckers for support and cheap parts. They do postal orders too.

Check your coil for cracks in it, or the plug wire. Carefully check for spark when the engine stalls and is hot. (Watch out for the toasty spark plug.) And then check for spark when the engine is stone cold... If you have spark when it is cold, and not when it's hot, then it could be the coil... However , your automatic choke could be a little screwy too.

Oh, pour fuel stabilizer in your tank in the reccommended concentration. Then run it, even if it has to be in ten-second spurts. This is a good time to have friends over. Try not to pour gasoline all over your favorite boots like I did, but disconnect the fuel line from the carb and confirm that there is fuel flowing. Odd things can get in there. Found a dead bumblebee plugging a fuel line once... You might need Torx drivers to work all your screws. My Craftsman had all Torx. I got a nice set at Home Depot for a good price.

It's got nothing to do with your gas cap. I had that issue on my four-cycle this spring, and although I never pinpointed the issue, here's what worked for me, after a fuel/air/spark check. I ripped mine apart and couldn't get the flywheel off, or I'd have took it to pieces and done an inch-by-inch inspection. Skunkbait's article on reviving old bikes applies to this situation. If everything looks okay, it's a small and nebulous gremlin in your intake setup. You might not need to rebuild your carb, I'm just an overachiever. :D Here's how I finally got my mower fixed: Look on top of your carb as the motor sputters and dies. There will be something springloaded moving back and forth when it shouldn't be. That, as far as I can tell, is the governor, and annoys me very much. Pull the cord and then poke the governor (might take two people). If you can get a positive response out of the engine by adjusting that little lever, Get your engine to self-sustain, even if that means holding the governor (I attached a wire to it that I'd pull on whenever things began coughing), and put a load on it by mowing. Turn it off, and while it's still hot, start it again. If it works, let it cool, then try to start it. If that works, you're golden. If not, wrestle it back to life, remove the air filter (away from lose dirt) and cover the hole with your leather-gloved hand. When the engine is just about to stop after a second or two, remove your hand. Let it cool and try to start it again. Dollars to donuts your problem is gone.

Check the fuel filter yet?
