Starting the engine
Use the P-I-T-Ch-Pull (pitch-pull) method to start your snowblower efficiently. Each step helps the engine get the right mix of air and fuel so it starts smoothly, even in freezing temperatures.
P: Prime the engine
Push the primer bulb 3 times for a cold start. Make sure you cover the vent hole on the bulb when pressing it in.
Tip: In very cold weather, you may need to prime again. For a warm engine, press the primer bulb only once.
I: Ignition is on
Push the key fully into the ignition switch. The engine won’t start if the key isn’t fully inserted.
T: Throttle in fast position
Move the throttle to the Fast or Rabbit position so the engine gets enough fuel to start properly.
Ch: Choke is set properly
Move the choke to the Full Choke position when starting a cold engine.
For a warm engine, place the choke in the Run position.
Pull: Pull the starter rope (or use the electric starter)
Use the starter to spin the engine.
Recoil starter: Pull gently until resistance builds, then pull quickly and forcefully. Return the handle to its position; don’t let it snap back.
Electric starter: Press the starter button to spin the engine. Press again if needed.
After the engine starts
As the engine warms up, gradually rotate the choke to the Run position. If the engine falters, restart it and use the half-choke setting for a short time before moving back to Run. Let the engine warm up for several minutes; it won’t reach full power until it’s at operating temperature.
Frequently asked questions about starting a snowblower
Can I use starter fluid to help start my snowblower engine?
Occasional small bursts of starter fluid are typically safe, but always check your owner’s manual first. Some engines can be damaged by overuse, so use it sparingly and only in small amounts.
Why does my engine stall a few seconds after starting?
A clogged carburetor is the most common cause. Old gas leaves deposits that block the carburetor jets. Cleaning or rebuilding the carburetor usually solves the problem.
See our guide: How to rebuild a snowblower carburetor.
What can cause my snowblower engine to lock up?
Common reasons include:
Hydrolock: Oil entered the cylinder when the snowblower was tilted. Remove the spark plug and spin the engine to eject oil.
Low oil: Refill and check for leaks if oil drains quickly.
Corrosion: A stuck piston may free up after soaking with penetrating oil for a day.
Mechanical failures: Seized bearings or valve issues may require engine or full snowblower replacement.
Why does my engine spin but won’t start?
A snowblower needs fresh fuel, spark, and compression. Check:
Gas freshness; replace if stale
Fuel filter and fuel line
Carburetor condition
Spark plug condition and gap
Stop switch function
