Spark Plug? Dirty fuel tank?

If both dirty replace spark plug, clean out the gas tank, and if needed, a new fuel line.

Check the air filter and the oil.

Reply with your results.

If you need replacement parts and I will see if I can find it online.

The fuel you put through the new carburetor. Did you get rid of the old fuel from the mower and gas can?

ALWAYS run fuel less than 31 days old. If you want to increase the freshness of the fuel, add Sta-Bil.

Check gaskets for corrrect install. Guys even bad fuel burns if it wont run there is something else going on. Spark plug and air filter are good idea might as well its about $10 for both.
