Craftsman String Trimmer Parts & Repairs

Craftsman string trimmers are built to last, but carburetors, trimmer heads, and fuel system parts wear out with seasonal use. Whether your Craftsman won't start, runs rough, or the trimmer head jams, Repair Clinic carries OEM parts that restore your trimmer to like-new performance.

The most common Craftsman string trimmer repairs involve the carburetor (ethanol damage clogs the jets and needle valve), primer bulb cracks, and trimmer head spools that get jammed from line breakage. Fuel lines harden in storage, spark plugs foul from old fuel, and throttle cables stretch or snap.

• Carburetor and Carb Kit: Hard to start, runs lean or rich, surging, stalls at idle; ethanol fuel damage is the #1 cause
• Trimmer Head / Bump Head / Spool: Line won't feed, spool jammed, won't load line; most common consumable part
• Primer Bulb: Cracked or won't draw fuel; priming failure prevents cold start
• Fuel Line & Fuel Filter: Cracked, clogged, or hardened from storage; fuel won't reach carburetor
• Spark Plug: Fouled from old fuel or carbon buildup; seasonal maintenance part
• Recoil Starter Assembly: Pull cord stuck, won't recoil, or snapped; starter rope jam is common
• Throttle Cable: Snapped or stretched; controls engine speed and won't engage properly

Craftsman String Trimmer Parts — Frequently Asked Questions

Why won't my Craftsman string trimmer start, and what part do I need?

The most common culprit is a dirty or clogged carburetor. Ethanol in fuel attracts water and gums up the carburetor jets, needle valve, and float. If your trimmer has been in storage for more than a few weeks, the fuel inside has likely gone stale. Start by trying a carburetor cleaning kit or fuel stabilizer. If that doesn't work, order a carburetor rebuild kit or replacement carburetor for your specific Craftsman model. A new spark plug ($3 to $5) and fresh fuel are also worth trying first. Check your model number (usually stamped on the engine or under the fuel tank) to ensure you get the correct carb — Craftsman trimmers use different carburetors depending on engine size.

What size trimmer head and line does my Craftsman string trimmer use?

Trimmer head size and line diameter vary by Craftsman model — typically.065" or.080" round line. Your owner's manual will specify the correct head type and line weight. Bump-feed heads are the most common Craftsman design; you advance the line by tapping the head on the ground, and the head automatically feeds new line. Universal heads are available but OEM Craftsman heads prevent jamming and fit the drive shaft properly. Always order by your model number to get the exact head assembly and spool kit — mixing wrong parts causes feeding problems.

My Craftsman trimmer runs but won't cut — what's wrong?

Check three things in order: (1) Line is present and loaded correctly in the spool; (2) Line isn't wrapped around the head or shaft; (3) Head itself is engaged and spinning. If the shaft spins but the head doesn't, the drive shaft coupling may be slipping or the head assembly is not seated. A new trimmer head spool or head assembly ($15 to $30) is usually the fix. If the head spins but line still won't come out, the bump feed mechanism is jammed — try running the head at full throttle and gently tapping it on grass to advance the line. If that fails, replace the trimmer head.

How do I find my Craftsman string trimmer model number to order the right parts?

Your Craftsman model number is typically printed on a label under the fuel tank, on the engine block, or near the handle. It usually starts with "CMXG" (electric) or a longer number sequence (gas). Write down the full model number before ordering any parts — carburetors, trimmer heads, and fuel system parts are model-specific. Enter your model number into the Repair Clinic parts finder, and you'll see exactly which parts fit your trimmer. Never assume two Craftsman gas trimmers use the same carburetor — they often don't.

Craftsman String Trimmer Model Number: Where to Look

Craftsman prints the model number on a label under the fuel tank, on the engine housing, or near the handle. Check the entire decal for the complete model and serial information, since similar string trimmers can use different parts. Once you have the model number, enter it in the model number search to pull up the parts matched to your unit. This filters the full Craftsman string trimmer catalog, including engine, fuel system, cutting head, and other associated parts, to options designed for your exact model. Using the complete number saves time and helps prevent ordering a part that looks right but does not fit.
