Craftsman Small engine stops after a few seconds
A Craftsman small engine runs then dies, stalls after starting, or runs for a few seconds and then cuts out, a clogged carburetor is the most likely cause. Stale or ethanol-blended fuel left in the carburetor, especially on seasonal equipment such as a lawn mower, can evaporate and leave a sticky residue that blocks the main jet and restricts fuel flow. Clean the carburetor with carburetor cleaner first. If the engine still starts but won't stay running, the carburetor may need a repair kit or complete replacement. A clogged carburetor float bowl, needle valve, or gasket can also prevent the correct fuel supply and cause the engine to die after starting. If the carburetor checks out, inspect the fuel cap. Its vent allows air into the fuel tank as fuel is used. A clogged vent creates a vacuum that stops fuel from reaching the carburetor. Loosen the fuel cap slightly and restart the engine. If it stays running, replace the fuel cap. Enter your model number to find the exact carburetor, repair kit, fuel cap, or other replacement part for your specific Craftsman engine.
01 - Craftsman Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the engine 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.

03 - Craftsman 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.
