Stop help: my lawnmower stop running after a few rounds and now it sputters when try to crank. - Help.com

Perhaps it just needs a good old-fashioned stiff kick. That usually does the trick.

There are few possibilities. You could have put in too much oil, you may have flooded the carborater with gas, or there could be air getting into the engine. Best bet if all else fails, bring it to someone who is certified to fix them.

Lawmmowers can be very cantankerous. There’s an actual case where a man kept pulling that doggoned start cord to start a new mower, and he pulled it so much he had a heart attack! His widow sued the lawn mower company and won–the court ruled that a new mower shouldn’t be so hard to start!

It’s not getting fuel after a while . . . I think the fuel lines may be clogged. Try some of that fuel injector cleaner in the gas tank and see if that helps!

Otherwise, just take it to a lawnmower repair shop!
