My craftsman lawn mower stalls .i changed the oil and fresh gas..air filter is clean

you may have some debris in your gas tank blocking the pickup tube. It will float away when the mower dies, then block the tube after it runs again.

Bad gas. Drain gas and refill with fresh gas with Stabil. Old oil. Drain oil fill with fresh 30w oil, 16-18oz. Clean air filter and spark plug.. Relpace air filter if dirty. Saving $$$ on this simple tune up is not intelligent.

try cleaning or changing the air filter

Charge battery to 12.8 volts or higher. 13.2 best. Below 12.8 volts replace battery. USE FRESH GAS ONLY. Always use Stabile in gas. Ensure oil is full. 30w. Clean or replace air filter.

Clean the Plug and replace the Seafoam gas with fresh. Althiough the Seafoam is a cleaning agent, it cuts back on the gasolines octane and it can slightly foul plugs.

it does sound like a carb issue it may need to be rebuilt also check your fuel line and if you have a fuel filter check the filter clean the gov. assembly with carb cleaner

Hi,
There is a kill switch under the seat that makes sure you stay in the seat if the mower is running...my bet is that the switch is malfunctioning and the vibration of the motor is causing it to short out...get a new switch, they can't be that much...

There are a few popular solutions for your problem. You can try changing out the old gas completely, with new fresh gas, you can try changing the spark-plug and air-filter. You can try cleaning the carburator or replacing it if you find it is broken. And you can try removing the spark-plug wire and putting in-line, a spark tester. The ark should be blueish white Not dull orange or yellow. If the spark is insufficient then you can try removing the pull-string cover and lightly sand the magnet that is on the fly-wheel and passes by the ignition coil. Good-luck.

Try changing the its oil-seals. The problem lies there. It may be damaged or the oil-seals are now smaller than its is used to and it is because of the heat. The oil-seal are rounded things that are made of rubber.

a mower will hold 20 oz of oil. however most times it is changed you do not not get it all out. so only 16 oz is needed. if you overfilled the oil. this would cause hard starting. or did you have the mower tipped on it's side for to long, oil can sometimes seep past the piston out thru your intake valve and into your carb as well as destroy you air filter. you might get by with a new oil change and a carb cleaning.


also has this unit been sitting for a while does it have fresh gas. and No water in the tank/carb
