Mower starts but won't stay running - Mtd 22" Yard Machine Push Mower

Ensure the oil is full. It has an oil low sensor. 30w oil.

Try cleaning the carburetor that might mean that it is not getting gas

sounds like carburetor is clogged or has something in the jets or possibly fuel line or tank is clogged. check fuel tank and line to make sure fuel flows easily then carburetor cleaning and rebuild may be required

I can't tell you how many pieces of small equipment I have been given for free because it "just won't start" or "won't stay running". Start by draining the tank and cleaning it out - use a good carb cleaner. It only takes a grain of sand to create a problem. You may have to take the carb apart and clean that out too.

All mowers have a low oil sensor, fill oil with 30w.

Either a problem with the seat switch, or just make sure the block connecter that gose to the switch is fully pushed into the switch if its even slightly off it will stop the engine.

It may not have a primer ball. If it does, it would be attached to the carberator. If it starts, but won't stay running, that could mean your carberator needs to be cleaned/serviced.

let it warm up with choke closed manually after it starts to stall with choke closed open it and dont let it stall u can learn to play with the choke a little to get it to run right GOOD LUCK!

Check the main jet holes.
