GCV200LA Carburetor Air Filter Tune Up Kit for Honda HRX217K6 Lawn Mower 16100-Z9M-811

What It Is

This is a genuine Honda GCV200LA tune-up kit containing the air filter, spark plug, and fuel filter needed for routine maintenance on Honda HRX217K6 lawn mowers equipped with the GCV200 engine. It’s designed to restore engine performance by replacing three wear items in one purchase.

Fitment & Compatibility

• Exact fit: Honda HRX217K6 mowers with the GCV200LA engine (check engine model stamp on valve cover or behind the air filter housing).
• OEM part number: 16100-Z9M-811 (air filter) + spark plug (NGK BPR6ES or equivalent) + fuel filter (16910-Z0L-803).
• Not universal: Will not fit other Honda GCV engine variants (e.g., GCV160, GCV190) or non-Honda mowers without verifying air filter dimensions (length ~4.25”, width ~2.5”).
• Deck size irrelevant: Compatibility depends solely on engine model, not cutting deck width (21” standard for HRX217).
• Check before buying: Confirm your mower’s engine model (e.g., GCV200, not GCV200LA) and that the spark plug gap is set to 0.028–0.031” before installation.

Key Things to Know

• Quality: Genuine Honda parts—aftermarket kits often use thinner foam in the air filter or shorter fuel filters that may not seal properly.
• Installation difficulty: Easy (15–20 minutes) with basic tools: screwdriver for air filter cover, pliers for fuel filter, and a spark plug socket (5/8”).
• Common gotcha: The fuel filter orientation matters—arrow on filter must point toward the carburetor. Installing backwards can cause fuel starvation.
• Performance gain: Expect smoother idle and faster throttle response if your old filter is clogged (common after 50–100 hours of use).

Should You Buy It

If you own a Honda HRX217K6 with the GCV200LA engine and want a plug-and-play maintenance kit that avoids fitment headaches, this is the right choice. It’s not for generic mowers or other Honda engine models, but for your specific machine, it’s a reliable, time-saving buy.
