The "less" refers to restarting it while it's warm. A light half-pull
turns it over.
However, just to be safe, when not in use I remove the sparkplug and
store it here:

One is supposed to run the engine until it runs out of gas, but even
that leaves some gas in the carburetor.
I'VE HAD GREAT RESULTS USING STA-BIL FOR THE LAST TWO FILL-UPS OF THE
SUMMER. ONE MOWER I DIDN'T USE FOR 18 MONTHS AND IT STARTED RIGHT UP.
I would never go into winter or fall without using it.

Before you do anything, put in a new plug. A plug can break down over
time, but still start and run. If that dosen't fix it, then you can
move on to other things like carb, timing (shear pin), valves and
etc..

Usually that will cause it to pop in the muffler when it stalls, fuel
builds up and fires.
If it just bogs and starts up again with no pop suspect fuel problems
or a governor sticking.

That's familiar to me. It often means the gas tank is nearly empty. I
think the carburetor is set to run as lean as possible at normal speed.
If it gets too lean and the engine slows, the governor opens the
throttle, which enriches the mixture enough to prevent stalling.
If it's a bowl carburetor, I'd shut off or clamp the fuel line and
unscrew the screw at the bottom of the bowl and catch the gas to see if
it has water or crud. I'd make sure the jets in the screw are clear.
I'd open the fuel line for a moment to see if the flow from the tank is
ample and see if there is any water coming from the tank.
