Pull cord won’t pull

The pull cord on the Pulsar PTG1221S may not work if the engine is flooded with excess fuel. This can happen if the starter has been pulled several times without the engine starting. To fix this, release the engine start/stop lever, remove and dry the spark plug, reinstall it carefully, then try starting the engine again.
