Stabilize fuel or drain it. Change oil. Inspect shear pins. Hose-clean the auger. Storing a wet, dirty snowblower is the leading cause of ones that won't start in November.

Run the engine until you can refill, dose stabilizer per label (1 oz / 2.5 gal), top up the tank, and run another 5 minutes so stabilized fuel reaches the carburetor. Stale untreated gas is the failure point in 8 of 10 spring no-starts.
Engine off, plug wire pulled. Drain warm oil into the pan. Tip the machine on the chute side, never the carburetor side, or oil floods the cylinder.
Refill with 5W-30 to the dipstick crosshatch. Most consumer snowblowers hold 18-20 oz. Overfilling is worse than underfilling - overfill smokes and fouls the plug.
Pull and inspect the spark plug. Gap is usually 0.030 in. - re-gap with a feeler or replace if the electrode is rounded.
Hose the auger housing clean. Brass-brush rust off the auger blades. Visible salt residue means the bearings are taking it too - rinse harder.
Inspect shear pins. If a pin is bent or showing fatigue lines, swap it. Always carry two spares; pins shear at the worst possible time.
Grease the auger shafts at the zerk fittings. One pump per fitting. Wipe the chute crank, work it through full travel - frozen chutes in February are a tune-up failure, not a winter event.
