Craftsman Generator Parts

Craftsman Generator Parts

Craftsman generators are built for dependable backup power, but like all gas-powered equipment, they're prone to a few predictable failures. The most common issue you'll run into is a carburetor that won't cooperate -- stale fuel and ethanol damage clog the jets, leaving you with a generator that cranks but won't fire. Spark plugs foul out, fuel lines crack, and the recoil starter can stick or fail entirely. We carry OEM Craftsman parts that match your exact model, so you're not guessing on part compatibility.

The good news: most Craftsman generator repairs are straightforward and inexpensive. A carburetor kit, spark plug, or fuel valve often gets the job done without replacing the whole engine. Enter your model number to find the exact parts you need -- Repair Clinic stocks OEM Craftsman generator parts with same-day shipping on most orders.

• Carburetor won't start or runs rough: Ethanol damage to float needle and jets; carburetor kit often fixes it
• Spark plug fouled or black: Old fuel or rich running condition; replace with correct heat range
• Fuel valve stuck: Petcock won't open to carb; fuel starvation; simple replacement
• Recoil starter stuck or won't snap back: Spring failure or internal rope jam; starter assembly replacement
• Generator produces no power output: Voltage regulator or AVR failure; test output voltage first
• Primer bulb cracked: Won't prime fuel to carburetor; low-cost replacement

Craftsman Generator Parts FAQs

What's the most common reason a Craftsman generator won't start?

Stale fuel and ethanol damage to the carburetor is the #1 culprit. If your generator has been sitting with fuel in the tank for more than 30 days, the ethanol in the fuel corrodes the carburetor's float needle, seat, and jets. A carburetor rebuild kit (or full carburetor replacement) solves it in most cases. If the carb is clean and fuel is fresh, check the spark plug next -- a fouled or gapped spark plug will prevent ignition even if everything else works.

How do I find my Craftsman generator model number for parts lookup?

The model and serial number are stamped or printed on a label attached to the frame or fuel tank of your generator. Common locations: near the top of the frame, on the side of the engine block, or on the fuel tank itself. Look for a number starting with "CMXG" (this is Craftsman's generator prefix). Once you have the full model number, enter it in Repair Clinic's parts finder to see the exact parts for your machine -- carburetor, spark plug, fuel valve, and all OEM parts will be confirmed for your specific model.

Is a carburetor rebuild kit enough, or do I need to replace the whole carburetor?

A rebuild kit is usually sufficient if the carburetor body itself isn't cracked or severely corroded. The kit includes a new float, needle, gaskets, and o-rings -- essentially all the wear parts. If the carburetor has visible cracks or the passages are severely varnished, a full carburetor replacement is the better investment. Either way, use the OEM Craftsman part -- aftermarket carburetors have higher failure rates on small engines.

Why is my generator losing power output or producing erratic voltage?

Check the voltage regulator or AVR (automatic voltage regulator) -- these parts maintain steady output. If your generator cranks and runs but power is low or fluctuating, the regulator has likely failed. Also verify that the outlet itself is clean and undamaged, and that you're not overloading the unit beyond its rated watts. Overloading can trip a breaker or damage the regulator. Replace the OEM regulator to restore stable power.
