Additional Information

The MTD Line Trimmer Carburetor (part number 751-16046-4) helps deliver a precise fuel-air mixture to the engine, supporting smooth and reliable trimmer operation. This part replaces earlier versions and is built to meet the original equipment specifications for select MTD models.

If your trimmer won?t start or surges while running, the carburetor could be clogged or damaged. Installing a new one can restore consistent engine function and improve fuel delivery.

Before beginning the replacement, make sure the trimmer is powered off and the engine is cool. Wear work gloves to protect your hands. Use a screwdriver and socket set to remove the old carburetor, then secure the replacement. Adjust the screws as needed for proper fuel-air balance?refer to your model?s service manual for settings.

Regular carburetor maintenance helps reduce hard starting and fuel inefficiency, keeping your line trimmer running as intended.
