Reason 1: Incorrect Fuel Type

Using the incorrect fuel type in a Craftsman lawn mower won’t run the engine for a long time.

Solution: Ensure the Accurate Fuel Type

To fix the trouble, through the wrong fuel away from the tank, and purify it. Search for the Craftsman lawn mower fuel type in the manual book and get that for the mower.

Reason 2: Carburetor is Clogged

A clogged carburetor is a result of using old fuel everytime.

Because old fuel carries a lot of dirt and it gets contaminated over time. And, the clogging starts coming to the carburetor and makes it blocked gradually.

Solution: Clean the Carburetor or Change It

To release the clogging from the carburetor, the effective solution is spraying a carburetor cleaner. Because it works too quickly and cleans so well. In case cleaning it doesn’t affect, change the carburetor soon.

Reason 3: Disconnected Ignition Coil

A disconnected ignition coil hinders the mower from running continuously. In case its connection with the electric unit gets loosened, no power can reach it.

Solution: Reconnect The Coil After Cleaning

First, you should clean the ignition coil and avoid any water. Then, inspect its wires and connect them in the correct way also with the electric unit.

Reason 4: Issues in Spark Plug

The electrode of a spark plug can get excessive dirt in it and it prevents the spark plug from working.

Over time, the electrode tends to get injured or worn out and this is a red flag for the plug. Consequently, the flow of sparks becomes irregular and the mower stops due to it.

Solution: Clean the Electrode and Spark Plug

As the electrode is the main suspect, clean it very carefully. Then, check for damages in it. You can not change only the electrode and that is why replacing the spark plug is the only way.

Reason 5: Clogged Fuel Hoses

Clogged fuel hoses are the noteworthy barriers for the flow of fuel. As fuel carries debris even after filtering, the hoses get clogged with them.

If the user is not regular in cleaning them, their condition becomes worse. Hence, the fuel pump and carburetor, let alone the engine, don’t receive fuel.

Solution: Remove the Clogging or Install New Hoses

Using compressed air, you can clean the hoses evenly. If the clogging is turned into a serious one, installing new fuel hoses is a must.

Why is My Craftsman Lawn Mower Starting and Then Turning Off?
