Hipa Courage Replacement Carburetor for Kohler 18/19/20 HP Engines — 20 853 33-S Kit with Gaskets & Filters

Hipa Courage 20 carburetor replacement kit is a complete drop-in replacement for Kohler Courage 18–22 HP engines that arrives pre-tuned and ready to install.

If your lawn tractor or mower with a Kohler Courage engine is running rough, flooding, or refusing to start, a worn or clogged carburetor is a common cause — and this Hipa kit is built to match OEM fit and function for several Kohler part numbers. The kit replaces 20 853 33-S (and equivalent numbers) and includes gaskets, filters, plugs, and hardware so you can restore fuel delivery and avoid multiple small parts orders.

Which Kohler engines and part numbers does this replace?

This Hipa carburetor is designed to fit a broad range of Courage-series Kohler engines and to directly replace multiple legacy part numbers.

• Compatible with Kohler Courage 20, 19 and 18 HP engines and related models.
• Specifically replaces 20 853 33-S, 20-853-33-S, 20-853-16-S, 20-853-14-S, KH 2085316-S and 2085314S.
• Works with engine codes often found on small tractors and mowers (SV600, SV590, SV540 series).
• Also fits equipment from Cub Cadet and Toro models that use the same carburetor footprint.

How is the kit packaged and what comes in the box?

Hipa supplies this carburetor as an all-in-one repair kit so you won’t need to source multiple components after purchase.

• Main Hipa 20 853 33-S carburetor x1 — fully assembled and tuned at the factory.
• Complete gasket set for mounting and mating surfaces to prevent leaks.
• Air filter and pre-filter to protect intake air cleanliness.
• Two fuel filters, an oil filter, and two spark plugs to refresh engine consumables during installation.

What are the key technical specs and materials I should know?

The Hipa unit is built to withstand heat and fuel exposure while maintaining reliable metering and spray characteristics.

• Mounting hole center-to-center: 52 mm to match Kohler mounting patterns.
• Throttle bore diameter: 26 mm; choke bore: 32 mm; venturi: 24 mm for correct airflow.
• Fuel inlet line diameter: 7.5 mm to fit standard fuel hose sizes.
• Construction uses brass jets, a zinc-plated float bowl, a high-density plastic float, and an anodized aluminum body for corrosion resistance and durability.

Will I need to adjust or tune anything after install?

The carburetor ships factory-tuned and wet-flow tested to simulate engine conditions, minimizing post-install adjustments for most installations.

• Factory tuning reduces initial setup — most users can install and start immediately.
• Wet flow testing ensures consistent fuel delivery and spray pattern under simulated load.
• Minor idle or mixture tweaks may be required for machines with aftermarket exhausts, air cleaners, or altitude changes.
• All mounting gaskets and filters included to streamline the service process.

Who is this for: The Hipa Courage 20 carburetor kit is aimed at DIY owners and small-engine mechanics working on Kohler Courage-series lawn tractors and mowers, plus compatible Cub Cadet and Toro models. If you want an OEM-fit replacement that arrives ready-to-run, includes consumable service parts, and matches the original carburetor’s mounting and bore dimensions, this kit saves time and avoids multiple part orders.
