Common solutions for: Snowblower starts then stalls
Solution 1:
Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time. Over time, some of the ingredients in the fuel may evaporate,... leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

Solution 3:
Fuel Cap
As fuel is consumed by the engine, the level in the fuel tank lowers. To make up for this, the fuel cap uses a small vent to allow air to enter the tank. If the fuel cap vent is clogged, air won’t be ...able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall. To determine if the fuel cap vent is clogged, try slightly loosening the cap and then starting the engine. If loosening the fuel cap allows the engine to stay running it is likely clogged and will need to be replaced.

Solution 4:
Spark Plug
Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark ...plug. To determine if the spark plug is defective, use a spark plug tester. You should see a strong spark between the tester’s terminals when the engine is cranking. If there is no spark, this indicates that the spark plug is defective and should be replaced.

Solution 5:
Engine Oil
The engine oil might have been overfilled. If the engine oil is overfilled, the oil may leak out through the breather and seep into the carburetor. If engine oil has seeped into the carburetor, remove... the carburetor and clean it thoroughly. Then ensure that the engine has the proper level of oil.
