All the other 4 cycle equipment that won’t (probably) be used until spring got a similar treatment (minus the oil, of course) Run empty, refilled with a bit of fuel that will evaporate and not leave residue or varnish behind, and run until completely empty.
This ensures they will start when needed after sitting for months.
I recommend this for all gasoline powered equipment.
Especially stuff you might need in an emergency.
Proper storage matters.
