Briggs engine/Troybilt no choke push mower won't start.

Changed spark plug, drained fuel tank and replaced with fresh gas. Mower used 6 times in 4 months, then wouldn't start. Has spark but won't start. Fuel line open after leaving gas tank. Tried starting with fuel cap loose, nothing. Blade shaft not bent. This is a no choke model that belongs to a friend.

Make sure that the choke plate is closing fully. You may have to adjust it.

If the old gas was left in it over winter without a fuel stabilizer it may need the Carb valves cleaned - I would try with a fuel cleaner and carb spray first and then, if necessary, take the carb apart and clean the jets. This gas with ethanol :thumbdown: gums up carbs and engines if you don't use a stabilizer for storage.
