FAQs

This kit is designed for Kohler 149cc engines, specifically the XT650, XT6.5, XT6.75, and XT675 series. It is commonly found on equipment from brands including Toro, MTD, and Husqvarna.
This unit replaces Kohler OEM part number 14 853 68-S (also written as 1485368S). It also serves as a direct replacement for 14 053 68-S.
If your mower is surging (hunting for idle), struggling to start, running roughly, or stalling shortly after starting, the carburetor is often the culprit. These issues are frequently caused by internal clogs from old fuel or degraded gaskets.
Yes. Ensure your fuel system is clean. If your old carburetor failed due to gummed-up fuel, drain your fuel tank and replace the fuel line and fuel filter included in this kit. Also, verify that the auto-choke linkage moves freely and is not binding during installation.
This carburetor is designed for standard gasoline. Avoid using fuel with an ethanol content greater than 10% (E10), as higher concentrations can degrade the internal components and lead to premature failure.
The installation is straightforward for most DIYers. You will typically need basic hand tools, such as a socket set and a screwdriver. The process involves removing the air filter housing, disconnecting the fuel line and choke linkage, and swapping the old unit for the new one. Expect the job to take about 30 to 45 minutes.
