Hey there, tractor and small engine folks! Is your Cub Cadet, Troy-Bilt, or other MTD-powered machine running rough, stalling, or just not starting like it used to? A worn-out carburetor might be the culprit. This Anxingo carburetor kit is a direct replacement for the common part numbers 993-00170 and 993-00170A. It’s designed to fit a range of machines powered by the MTD 4X90HU and 4X90HUA 547cc engines. That includes models like the Cub Cadet XT1-LT42 tractor (2015-2016), and various other Cub Cadet, Troy-Bilt, and MTD equipment using that engine family. The kit includes the complete carburetor AND three necessary gaskets, so you have everything you need for the swap. It’s built from durable metal materials to deliver a consistent fuel-air mixture, which is key for smooth engine operation, good fuel efficiency, and reliable power. Installing a fresh carb can often bring an old engine right back to life, eliminating hard starts and poor performance. Before ordering, just double-check your engine model number to ensure a perfect fit. A straightforward fix to get your yard workhorse running strong again!
