MDAIRC SV600 Carburetor Replacement Kit for Kohler Courage SV600 SV610 — Complete Gasket & Filter Service Kit

The MDAIRC SV600 carburetor is a complete direct-replacement carburetor kit built to restore proper fuel delivery on Kohler Courage engines (SV470–SV620 series) used in 15–22 HP riding mowers.

If your mower is running rough, stalling, or failing to reach full throttle, a worn or clogged carburetor is a common cause. This MDAIRC assembly is designed to match OEM mounting and port locations for Kohler Courage engines—covering models such as SV470, SV471, SV480, SV530, SV540, SV541, SV590, SV591, SV600, SV610 and SV620—and includes gaskets, filters, lines, clamps and other installation parts so you can replace the entire fuel-delivery unit in one service.

Will this carburetor fit my Kohler Courage engine?

The MDAIRC SV600 kit is engineered for compatibility with many Kohler Courage engines and associated mower models. Check your engine model stamp and compare mounting bolt pattern and throttle linkage to confirm fit before purchasing.

• Fits Kohler SV470–SV620 series including SV600 and SV610 models.
• Compatible with many MTD, Toro and Troy-Bilt lawn tractor models that use these Kohler engines.
• Matches common OEM part numbers referenced for Courage-series carburetors.

What parts are included and why the full kit matters?

Beyond the carburetor body, this package supplies all peripheral items frequently replaced during a carburetor service. Having the extra gaskets, lines and filters prevents extra trips for missing parts and ensures a proper seal and clean fuel path after installation.

• Includes carburetor, fuel line, two gaskets and wire connector.
• Supplies air filter, pre-cleaner, fuel pump, fuel and oil filters, clamps and a spark plug.
• Also includes a fuel shutoff valve and fuel filter for a complete refresh of the fuel system.

How do I diagnose and adjust surging or idle issues after install?

Engine surge or unstable idle can be caused by incorrect idle mixture or air leaks. The kit includes an adjustable nut on top of the carburetor; small turns of that nut often stabilize the idle. Always make adjustments incrementally and test under safe conditions.

• If the engine surges, slightly loosen or tighten the top-side adjusting nut to find a steady idle.
• Confirm all gaskets and clamps are tightened to prevent vacuum leaks that cause instability.
• Replace fuel and air filters from the kit to eliminate clog-related performance problems.

How difficult is installation and what tools are needed?

Installation is straightforward for anyone familiar with small-engine maintenance; basic hand tools and a clean workspace are sufficient. The included parts simplify the process because you won’t need to source separate gaskets or lines.

• Typical tools: socket set, screwdrivers, pliers, carburetor cleaner and torque wrench for critical bolts.
• Allow time to drain fuel, remove old carburetor, swap gaskets and reconnect linkages and fuel lines.
• Follow safety steps: disconnect spark plug and work with engine cool and well-ventilated.

Who is this for: The MDAIRC SV600 carburetor kit is intended for owners, DIY mechanics, and small-engine technicians who need a reliable, all-in-one replacement for Kohler Courage engines on 15–22 HP lawn tractors and riding mowers. It’s ideal when you want to replace a failing carburetor and refresh related fuel system components in a single service, restoring smoother throttle response, more consistent idling, and dependable startup without sourcing multiple parts separately.
