Toro snowblower won’t stay running. There are several common reasons for this issue, as well as their solutions.

Clogged Carburetor

Generally, a clogged carburetor is caused by leaving fuel in the snowblower for too long. During the evaporation process.

Some of the ingredients leave behind a thicker, stickier substance that can clog up the carburetor and prevent it from running.

If cleaning with other substances doesn’t solve the problem you may need to replace or rebuild your carburetor altogether.

Defective Fuel Cap

As fuel is used by the engine, the level in the tank drops. The fuel cap uses an air vent to make up for this level difference and keep a vacuum from forming within the tank.

If the air vent is clogged then no air can get into the tank and a vapor lock will occur, which stops fuel from getting to the carburetor and causes your snowblower to stall.

To determine if your snowblower has a clogged fuel cap vent simply try slightly loosening it while the engine is running.

If loosening your fuel cap allows it to stay running most likely it’s being obstructed by gunk inside of there and will need to be replaced with a new one.

The engine oil may have been overfilled

Carburetors may contain oil. This means that the oil might leak due to overfilling.

When you spill engine oil into a carburetor, take it apart and clean it thoroughly inside since otherwise, it could mess up with the other elements in its system.

Defective Spark Plug

Inspect the spark plug and compare it to the new one that is being installed. If the rubber boots around the electrodes appear cracked.

Worn, or when a large amount of carbon buildup appears at the end of this component, then the spark plug should be replaced.

To determine if a spark plug is defective you can use a specialized tester that utilizes a small amount of electric current to send some high-voltage across its terminals.

If there is no sound and/or sparking between these two points when cranking up your engine, then this indicates that the spark plug has likely broken down and should be replaced immediately.

FAQs

A Toro snowblower carburetor can be adjusted in several ways.

Warm up the engine of the Toro snowblower for five minutes by turning it on. Switch to the “Fast” position after the engine has warmed up.

Rotate your power level adjustment  1/8-turn at a time (to fast, then to slow, and so on) until you hear an erratic sound from your engine.

Next, turn the power level down one full turn, then move it up 1/4-turn increments from there.
