AUTOKAY GCV190 Carburetor for Honda GCV 190 GCV190A GCV190LA Engine HRB217 HRX217 HRX217K1 HRX217K2 Lawn Mower 16100-Z0Y-813 with Air Filter and Spark Plug

What It Is

This is a complete carburetor replacement kit for Honda GCV190 engines, used primarily on Honda HRB217 and HRX217 series walk-behind mowers. It includes the carburetor, air filter, and spark plug, designed to fix starting issues, rough idling, or poor performance caused by a clogged or failed carburetor.

Fitment & Compatibility

Before buying, confirm your engine is a Honda GCV190, GCV190A, or GCV190LA. The carburetor fits models HRB217, HRX217, HRX217K1, and HRX217K2. It replaces OEM part number 16100-Z0Y-813. This is an aftermarket part, not genuine Honda. Check your mower’s model number (on the frame under the seat or near the rear wheels) and engine code (stamped on the blower housing). The carburetor is a direct bolt-on replacement; no modifications are needed if your engine matches. Measure the mounting bolt spacing (typically 60mm center-to-center) and the fuel inlet size to be sure.

Key Things to Know

• Quality variance: Aftermarket carburetors often need minor adjustment (idle screw, float level) out of the box. Expect some tuning after installation.
• Installation difficulty: Moderate. You’ll need basic hand tools (socket set, screwdrivers, pliers) and about 30–60 minutes. Watch a YouTube tutorial for your specific mower model.
• Common gotchas: The included spark plug may not match your engine’s gap spec (usually 0.028–0.031 in). Always gap it correctly. Also, the air filter may be slightly different from OEM—check fit before installing.
• Return policy: Since it’s aftermarket, some sellers have strict return windows for carburetors. Test fit immediately.

Should You Buy It

If your Honda GCV190 mower is hard to start, runs rough, or stalls under load, this kit is a cost-effective fix—around 1/3 the price of an OEM carburetor. It’s best for DIYers comfortable with basic engine tuning and willing to adjust the carburetor after install. If you want a perfect, no-fuss replacement or have a newer mower, stick with genuine Honda parts.
