NIMTEK GCV170 Carburetor with Air Filter for Honda GCV170LA G5B GCV170LA G5BR GCV170LA S3B Models Lawn Mower Pressure Washer Replace 16100-Z9L-811

What It Is

This is a complete carburetor assembly with an integrated air filter, designed for Honda GCV170 engines found in push mowers and pressure washers. It replaces the OEM Honda 16100-Z9L-811 carburetor and restores fuel delivery and air filtration to get the engine running smoothly again.

Fitment & Compatibility

Before buying, confirm your engine’s specific model number—this carburetor fits Honda GCV170LA G5B, G5BR, and S3B engines only. Check the engine label (usually stamped on the blower housing or under the fuel tank) for the exact model code. It will NOT fit GCV160, GCV190, or older GCV170 variants without the “LA” suffix. Measure the mounting bolt spacing (approximately 60mm center-to-center) and ensure your throttle/governor linkage matches the G5B/S3B style. This is an aftermarket replacement, not genuine Honda, so verify the gasket and air filter housing align with your existing intake manifold.

Key Things to Know

• Quality: NIMTEK is a budget aftermarket brand; the carburetor may require minor adjustment of the idle mixture screw (if adjustable) and throttle linkage. Expect plastic components that are less durable than OEM.
• Installation difficulty: Moderate—you’ll need to remove the old carb, transfer the fuel line, and reconnect the governor spring and throttle cable. No special tools beyond a screwdriver and socket set.
• Common gotchas: The included air filter may be slightly smaller than OEM; check the seal around the housing. The carburetor may need cleaning of debris from manufacturing (blow out jets with compressed air). If the engine runs rough, adjust the idle speed screw (turns out for higher idle).
• Fitment note: Works on pressure washers with GCV170LA engines, but the throttle linkage setup may differ—verify your model’s cable type before ordering.

Should You Buy It

Buy this if you have a confirmed Honda GCV170LA G5B/G5BR/S3B engine and need a quick, cheap fix for a clogged or failing carburetor. It’s a solid budget option for DIY repairs on older mowers or pressure washers, but skip it if you want OEM reliability or have a non-LA engine variant—stick with genuine Honda or a higher-quality aftermarket brand for better fit and longevity.
