Craftsman Lawn Mower Fuel Shut-Off Replacement

Genuine Craftsman Lawn Mower Fuel Shut-Off Valve & Float Parts

The fuel shut-off solenoid and float valve are the heart of your Craftsman carburetor's fuel management system. When the solenoid sticks or the float gets stuck, fuel overflows into the engine, drowning it and causing black smoke, hard starting, and fouled spark plugs. Repair Clinic stocks OEM Craftsman fuel shut-off valves and float kits to restore carburetor precision and engine reliability.

These small but critical parts prevent fuel from flowing when the engine shuts down and regulate float height for perfect fuel-to-air ratio during operation. A stuck float or failed solenoid means your carburetor can't feed the engine correctly, leading to starting problems and poor mowing performance.

• Fuel shut-off solenoid valve: Engine starts then stalls, or fuel flows when mower is off
• Float needle and seat: Carburetor overflowing fuel into bowl or leaking from overflow tubes
• Float arm assembly: Improper fuel level causing rich or lean running condition
• Solenoid plunger: Engine won't prime or fuel won't shut off at ignition cutoff
• Float bowl gasket: Fuel pooling around carburetor base or dripping onto engine block

Check your Craftsman frame tag for the model number, then locate your Craftsman lawn mower fuel shut-off and float parts to fix carburetor flooding and starting issues.

Craftsman Lawn Mower Fuel Shut-Off & Float FAQs

What does a stuck float in my Craftsman carburetor cause?

A stuck float needle sits too low or too high, throwing off fuel level in the bowl. Too high and fuel backs up and spills out the overflow tube or into the engine, causing flooding, black exhaust smoke, and hard starting. Too low and the engine starves for fuel, losing power or stalling mid-mow. The float assembly must move freely for proper carburetor function.

Why is my Craftsman lawn mower leaking fuel after sitting overnight?

The fuel shut-off solenoid should cut power when you turn the key off, closing the valve and stopping fuel flow. If it sticks open, gravity feeds fuel down through the carburetor into the crankcase or out the overflow tube. A replacement solenoid prevents fuel leaks and engine flooding overnight.

Can I clean the float needle and seat instead of replacing them?

Varnish buildup from old fuel can sometimes jam the needle, and gentle soaking in carburetor cleaner helps. However, if the needle tip is worn or the seat is pitted, cleaning won't restore a proper seal. OEM Craftsman float needle and seat kits are inexpensive and ensure your carburetor meters fuel exactly right.

How do I know if it's the solenoid or the float causing my flooding problem?

If fuel leaks only when the engine is off, it's usually the solenoid not shutting off fuel flow. If fuel overflows while running, especially after first startup, the float is likely stuck or set too high. A Craftsman carburetor rebuild kit includes both parts, making full restoration fast and reliable.

Craftsman Lawn Mower Model Number: Where to Look

On Craftsman lawn mowers, look for the model number on a label attached to the frame near the blade deck, beneath the seat, or on the engine housing. Clean dirt from the tag so every letter and number is easy to read, and copy the full model number exactly, including any periods or letters. Enter it in the model number search to pull up the complete selection of parts matched to your mower. The model number applies to the entire unit, so it narrows every related parts category to parts designed for your specific Craftsman lawn mower. That means fewer wrong orders and a faster repair.
