Kohler Small Engine Carburetor Parts & Rebuild Kits

Kohler engines power everything from pressure washers to generators to go-karts — and when ethanol fuel sits in the carburetor over winter, varnish builds up inside. The needle and float corrode, jets clog, and your engine won't start or runs rough. A Kohler carburetor rebuild kit or complete carburetor replacement solves most cold-start and running problems without replacing the entire engine.

Kohler carburetors vary by engine displacement and year, so entering your exact engine model number (stamped on the engine block, not your equipment model) ensures you get the right fuel bowl gasket, needle seat, float, and jet set. OEM Kohler carbs maintain the precise fuel-air mixture your engine needs.

• Hard start or won't start: varnish in carburetor jets; rebuild kit often fixes it
• Runs rough or stalls: float stuck, needle corroded, or jet clogged
• Rich running (black smoke, fouled plug): needle stuck open; carburetor rebuild or replacement
• Lean running (surging, backfiring): jets worn or air leak around bowl gasket
• Fuel leaks from bowl: float has hole or needle seal failed; replace carburetor assembly

Kohler Carburetor FAQ

What size carburetor do I need for my Kohler engine?

Kohler carburetors are displacement-specific — a K582 (14 hp) uses a completely different carb than a K341 (10 hp). Find your engine model and displacement on the engine block itself (not your equipment), then use Repair Clinic's model lookup to confirm the correct carburetor assembly. Ordering by engine model number takes the guesswork out of fit.

Should I rebuild or replace my Kohler carburetor?

If your engine won't start or runs rough after sitting all winter, a Kohler carburetor rebuild kit is usually the first move — it's a $15 to $30 fix. Disassemble, soak the parts in carburetor cleaner, replace the gasket, needle, and float, then reassemble. If the carburetor body is cracked, the needle seat is damaged beyond repair, or the float is punctured, a complete OEM replacement carburetor is the right call. Aftermarket carbs often have fit and mixture issues on Kohler precision engines.

What's included in a Kohler carburetor rebuild kit?

A genuine Kohler rebuild kit typically includes the fuel bowl gasket, inlet needle and seat, float, jet set (main jet, idle jet), and gasket seals — everything that wears or corrodes from ethanol fuel exposure. Not all kits include the float bowl assembly itself, so check the kit contents against your parts diagram to make sure you have every wear item.

How do I know if my Kohler carburetor has a fuel bowl gasket or a diaphragm?

Kohler engines use both styles depending on the year and displacement. Look at your carburetor bottom — if there's a removable bowl held by a single bolt, it's a bowl with gasket. If the bottom is sealed and you see a thin rubber diaphragm membrane, it's a diaphragm carb. Your engine model number determines which style — enter it in the Repair Clinic lookup and the correct rebuild kit will appear. Mixing styles is a common mistake and causes fuel leaks or running problems.

Kohler Small Engine Model Number: Where to Look

On Kohler small engines, look for the model number on the engine itself, typically on the cooling shroud, valve cover, or engine cover. It may appear on a metal plate, sticker, or stamped label alongside the specification and serial information, so copy the complete model designation carefully. Do not use the model number from the surrounding equipment if it has one; the Kohler engine number identifies the engine fitted to your unit. Type it into our model number lookup and the catalog narrows to parts made for your unit. This filters the full Kohler small-engine selection, not just carburetor parts, helping you compare compatible parts without sorting through mismatched versions. It is the quickest way to be sure the part fits before you order.
