Homelite Genuine OEM Replacement Carburetor # 308054114

What It Is

This is a genuine OEM carburetor (part # 308054114) for Homelite string trimmers, brush cutters, and handheld blowers. It meters the fuel-air mixture for combustion, directly replacing a worn or clogged factory unit.

Fitment & Compatibility

• Check your model number: This carburetor fits select Homelite 2-cycle handheld tools—common models include UT20600, UT20620, UT20622, UT20624, UT20630, UT20640, UT20650, and UT20660. Not universal.
• OEM vs aftermarket: This is a genuine Homelite part, not a generic. Expect exact fit and no adapter modifications.
• Measurements: The carburetor has a standard 2-bolt mounting pattern with 42mm centers. Gasket and primer bulb are often included in the kit—verify before ordering.
• Fuel line size: Uses 3/16” ID fuel line. If your lines are brittle, replace them at the same time.

Key Things to Know

• Quality: Genuine OEM means better tolerances and longer life than most $15 aftermarket carburetors. Expect fewer starting issues and a stable idle.
• Installation difficulty: Moderate. You’ll need to remove the air filter cover, old carb, and transfer the primer bulb and fuel lines. A small screwdriver and pliers are enough.
• Common gotcha: The gasket and diaphragm can be installed upside down. The raised lip on the gasket must face the carb body. Reversing it causes flooding.
• Pre-install check: Clean the fuel tank and replace the fuel filter. Debris from old fuel will clog the new carb quickly.

Should You Buy It

If you have a compatible Homelite model and your current carb is leaking, hard-starting, or won’t hold a tune, this is the right fix. It’s pricier than generic replacements but saves time on tweaking and returns. Best for DIYers who want a drop-in, no-hassle repair.
