What It Is

This is an aftermarket carburetor assembly designed to replace the factory carb on Kohler XT675 and XT650 149cc engines, commonly found on Toro Recycler and MTD walk-behind mowers. It includes the auto choke mechanism and is intended for engines that won’t start, run rough, or stall due to clogged or failed OEM carburetors.

Fitment & Compatibility

Before buying, confirm your engine model is Kohler XT650 or XT675 (149cc). Check the OEM part numbers on your current carb: this unit replaces 14 853 68S, 14 853 68-S, 1485368S, 14 853 68, 1485368, and 14 853 55-S. It fits Toro Recycler models with these engines, but not all Toro mowers—verify your mower’s model number (often under the seat or on the frame). Measure the mounting bolt spacing (typically 2.5 inches center-to-center) and the intake flange size (45mm) to ensure a match. This is an aftermarket part, so gasket quality and jet sizing may differ slightly from OEM.

Key Things to Know

• Quality varies: Many users report it works fine out of the box, but some need minor adjustment to the idle mixture screw or float height. Expect to clean off machining debris before installation.
• Auto choke setup: The auto choke is pre-set, but if your engine floods or won’t start, check that the choke plate moves freely. The bi-metal spring can be sensitive to heat soak.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, fuel line, and linkage. A carburetor rebuild kit is not included—buy one separately if you prefer rebuilding over replacing.
• Common gotcha: The gasket provided may be thin or misaligned. Use a thin layer of gasket sealant or order an OEM gasket for a better seal. Also, the fuel shut-off solenoid (if your mower has one) may not fit—check compatibility.

Should You Buy It

Buy this if your Kohler 149cc engine is hard-starting or stalling and you want a budget-friendly, drop-in replacement that mostly works. It’s right for DIYers comfortable with basic carb work and willing to tweak settings. Skip it if you need exact OEM fitment, have a complex auto-choke system, or prefer a rebuild over replacement—then stick with a genuine Kohler carb.
