VNATVU Carburetor for Riding Mowers 42/46-inch – Direct-Fit for 13.5–21HP Briggs & Stratton, Restores Smooth Start

VNATVU replacement carburetor engineered to restore smooth starting and consistent throttle response for compatible Husqvarna, Craftsman and Poulan Pro lawn tractors with 14.5–21HP Briggs & Stratton engines.

If your riding mower hesitates at idle, bogs under load, or struggles to start, a worn or damaged carburetor is often the culprit. This VNATVU unit replaces OEM carbs listed for models such as Husqvarna YTA18542, YTH2042, and similar Craftsman, Poulan Pro, Troy-Bilt and LT-series tractors. It’s made to match the mounting, throttle linkages and fuel passages of common Briggs & Stratton 13.5–21HP overhead valve engines so you can get back to mowing quickly.

This carburetor is compatible with a wide range of lawn tractors from Husqvarna, Craftsman, Poulan Pro and Troy-Bilt that use small Briggs & Stratton engines.
