XT675 Carburetor with Fuel Filter for Kohler XT650 XT675 XT6.5 XT6.75 Toro MTD Lawn Mower Replace 14 853 55-S

What It Is

This is a complete carburetor assembly with a fuel filter, designed to replace the OEM Kohler 14 853 55-S on small horizontal-shaft engines. It’s meant for residential mowers (Toro, MTD, Craftsman, etc.) using Kohler XT650, XT675, XT6.5, or XT6.75 engines.

Fitment & Compatibility

• Check your engine model number – Must be Kohler XT650, XT675, XT6.5, or XT6.75. Look for a sticker on the engine shroud or valve cover.
• OEM replacement – Directly replaces Kohler part #14 853 55-S. If your mower uses that OEM part, this should fit.
• Physical dimensions – Two-bolt flange, single-barrel, with a metal bowl. Measure your old carb’s mounting hole spacing (approx. 2.25” center-to-center) and bowl diameter (approx. 2.5”) to confirm.
• Fuel line size – This carb uses a 1/4” fuel line. If your mower has 5/16” line, you’ll need an adapter or step-down fitting.
• Common mower brands – Toro Recycler, MTD Yard Machines, Troy-Bilt, Craftsman – but verify engine model, not just brand.

Key Things to Know

• Quality is mixed – Several users report it works well after cleaning out machining debris. Others note it may need a gasket set (not included) if the supplied gaskets don’t seal perfectly.
• Installation difficulty – Moderate. You’ll need to remove the old carb, transfer the throttle/governor linkage, and adjust the idle mixture screw (usually 1.5 turns out as a starting point).
• Fuel filter included – A small inline filter is provided, but it’s basic. Consider replacing it with a high-quality brand filter for better debris protection.
• Common gotcha – The carb may arrive with a clogged main jet from manufacturing dust. Use compressed air or a fine wire to clear it before installing.
• No warranty – This is an aftermarket part; returns are handled by the seller, not Kohler.

Should You Buy It

If you have a Kohler XT-series engine with a failed OEM carb and want a budget fix for a season or two, this is a reasonable option. But expect to spend extra time cleaning and tuning it. For a more reliable long-term solution, pay double for a genuine Kohler carburetor.
