What It Is

This is a direct-replacement carburetor for Honda GC190, GCV190, GCV190A, and GV190LA engines, commonly found on Honda HRB217 and HRX217 series lawn mowers. It manages the fuel-air mixture to keep the engine running smoothly and is a common fix for hard-starting, surging, or stalling issues.

Fitment & Compatibility

Before buying, confirm your engine model (stamped on the valve cover or shroud): GC190, GCV190, GCV190A, or GV190LA. This carb replaces Honda OEM part numbers 16100-Z0Y-813, 16100-Z0Y-812, 16100-Z0Y-003, 16100-Z0Y-811, and 16100-Z0Y-013. It fits HRB217 and HRX217 mowers (including K1 and K2 variants), but double-check your specific mower model number—some older HRX217 models may use a different carb. This is an aftermarket part, not genuine Honda, so expect minor differences in gasket quality or finish. No deck size check needed; engine model is the only compatibility factor.

Key Things to Know

• Quality variance: This aftermarket carb often works well, but some units may have loose screws or poor gasket fit. Inspect and tighten everything before installation.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, fuel line, and throttle linkage. Budget 30–60 minutes; have a small screwdriver and pliers ready.
• Common gotcha: The float bowl screw is fragile—don’t overtighten. Also, old fuel lines may crack when removed; replace them if they’re hard or brittle.
• Adjustment needed: Unlike OEM, you may need to tweak the idle mixture screw (if present) or clean out debris from shipping. A quick spray of carb cleaner before install helps.

Should You Buy It

If your Honda mower is hard-starting or surging and you’ve confirmed the engine model above, this is a budget-friendly fix that often works as well as the OEM part for a fraction of the cost. It’s best for DIYers comfortable with basic small-engine work, not for those wanting a drop-in, zero-hassle replacement.
