My husbad even pushed it about 3 foot steps and it stopped running. What could be the effect of mower stop running. This mower is only 1 yr old
Small engines hold one of two issues: fuel or spark. If the engine runs for a short time, it is most likely a fuel issue. Did you drain the fuel over the winter, or put fuel stabilizer surrounded by? If you did not, you may have gummed up the carbeurator. If this is the case you will obligation to remove the carb and clean up all of the individual components, it is most predictable a jet issue. Good luck


The carburetor may be installed resting on the gas tank. If it is there is a small tube that runs from the bottom of the carburetor to the inside of the fuel reservoir. On the bottom of that tube is a very fine screen. That blind is clogged, preventing fuel from reaching the motor. Simply remove the carburetor and clean the screen. The mower should start against the clock and run fine afterward I will guess that the engine is a Briggs and Stratton. If it is it mostt likely has a diaphram carburetor. The carburetor it attached directly to the fuel container. You will have to remove the fuel tank and than the carburetor. Get a tentative diaphram and gasket from a small engine repair shop and install it. Make sure the carburetor and the fuel tank are clean.
Answers:    previously you get into removing the carb, it may be a little simpler. the 3rd factor of an engine is air. on the side of the engine is a grated cover held on with a screw or thumbscrew that covers the atmosphere filter. remove the filter and re-start. if it runs then you just obligation to clean or replace filter. while you have the filter sour, get some spray carb cleaner and spray it into the hole that the air filter be covering(you would be looking at the carb intake). try to run again.
lastly: under the carb which you are looking at is a round metal bowl, usually aluminum colored, and has a nut on the bottom. drain the reservoir again. remove the hose attached into that bowl, plug it if there is any leftover gas. remove the bowl by unscrewing that nut. frequently you can procure junk trapped there which plugs up the fuel to the carb. verbs the bowl, re-assemble, refuel, prime the carb by shooting the carb cleaner in the carb, and try again.
Hope That helps. Good Luck!
