SOURCE: Stuck pull cord on Toro 6.5 self-propelled mower
1) Common problem when a mower sits for several weeks at a time between mowing;
check for extra grass debris to be glogged between the blade and the mower shell.
2) If the mower has a 'bail' or 'zone' control handle;
this releases a brake mechanism on the flywheel to allow it to rotate, and after it is running, releasing the lever will 'kill' the engine.
NOTE* when transporting a push mower in the trunk of a car, try to keep the mower as level as possible.
*extra note when mower has been transported in the back of a car;
sometimes the mower is placed in a trunk at such a severe angle that the oil from the crankcase is forced around the rings and sits on top of the piston so that when you try to pull the rope you have a 'hydra' lock. (that is when a liquid is between the piston and the spark plug) You cannot compress a liquid, so the rope appears stuck.
If this happens, remove the spark plug (make sure the loose plug wire is fastened away from any combustable that comes out of the spark plug hole *** AND THERE WILL BE A HUGE STREAM OF OIL AND GASOLINE, SO BE PREPARED TO CLEAN UP A MESS ***
pull as normal until fluid is dispelled from internal engine
clean or replace the spark plug
a few more pulls (no choke required) and you are up and going
