Weed Eater String Trimmer Parts

Weed Eater trimmers are one of the most common gas string trimmers in the field — millions sold through Sears and Walmart over decades. When your Weed Eater won't start, runs rough, or won't feed line, the fix is usually simple and inexpensive. We carry OEM Weed Eater parts for every major series: carburetors, primer bulbs, fuel lines, spark plugs, trimmer heads, recoil starters, and throttle cables.

The most common Weed Eater repairs involve the carburetor (ethanol damage clogs the jets), trimmer head/spool (line won't feed or gets jammed), and fuel system parts (cracked lines, bad primer bulbs). Weed Eater Parts are affordable and easy to replace — most jobs take under an hour with basic tools.

• Carburetor kits: Hard start, runs rich, won't idle; ethanol damage to float, needle, or jets
• Trimmer head / bump head / spool: Line won't feed, gets jammed, or head spins but line doesn't advance
• Fuel line and primer bulb: Cracked fuel line or cracked primer bulb won't draw fuel
• Spark plug: Maintenance item; black/fouled plugs from old fuel
• Recoil starter: Pull cord stuck, won't recoil, or rope is frayed

Weed Eater Trimmer FAQ

Why won't my Weed Eater start?

The #1 reason Weed Eater trimmers won't start is a clogged carburetor from stale fuel and ethanol damage. If the trimmer sits more than a month without fuel stabilizer, the carburetor jets get blocked. A carburetor rebuild kit or full replacement carburetor solves this 80% of the time. Second most common: a cracked fuel line or bad primer bulb that won't draw fuel. Check the fuel line for splits and the primer bulb for cracks before ordering parts.

How do I find my Weed Eater model number?

The model number is stamped on the shaft tube or the motor housing, usually near the base of the engine. It looks like a series of digits or alphanumeric code (e.g., WE13A, WT3100, GHT18). Enter your model number into the Repair Clinic search bar and we'll show you the exact parts that fit — carburetors, gasket sets, ignition modules, and all fuel system parts are model-specific.

Why isn't my trimmer head feeding line?

Trimmer head problems are the second most common Weed Eater repair. The spool can jam if line is wound too tight, the bump knob can crack and stop advancing line, or the head itself can break. OEM Weed Eater trimmer heads are inexpensive and swap in quickly — measure your head diameter (usually 0.080" or 0.095" line size) and order the exact head for your model. Don't use universal heads if you can avoid it.

What's the difference between a carburetor kit and a full carburetor?

A carburetor kit includes the gasket, diaphragm, needle, float, and all internal parts — it rebuilds your existing carb. A full carburetor replacement is a complete new unit. For Weed Eater trimmers, a kit is usually sufficient unless the main body is cracked or the threads are stripped. Kits are also cheaper. If the kit doesn't solve the starting issue, move to a full carburetor replacement.

Weed Eater String Trimmer Model Number: Where to Look

On Weed Eater string trimmers, look for the model number on the shaft tube or motor housing, typically near the base of the engine. Check the equipment label carefully since the model code may appear alongside the serial number and other specifications. Once you have it, enter the number in Repair Clinic's model lookup to narrow the complete catalog to parts made for your specific trimmer, including engine, fuel-system, ignition, starting, and cutting parts. Matching the model before you shop saves time and helps you avoid ordering parts based on appearance alone. You will have a faster, more accurate path to the correct repair.
