Small Engine
Honda GX200
4-Stroke
The Honda GX200 is a 196cc 4-stroke overhead-valve engine and the primary powerplant for Honda-branded pressure washers up to 3,000 PSI, entry-level generators, tillers, and plate compactors. One of the most commonly serviced small engines in North America due to its widespread OEM use. It uses a Keihin float-type carburetor and accepts NGK BPR6ES or Champion RC12YC spark plugs. Routine maintenance every 100 hours: oil change (SAE 10W-30), air filter service, and spark plug inspection. The carburetor main jet, float, and needle are the primary wear items on high-hour GX200s.

Before You Buy
- Confirm the full model is Honda GX200, not just the family name.
- Check serial number, production date, and regional variant before ordering.
- Match the old OEM number stamped on the removed part when available.
- Compare dimensions, plug gap, thread, fuel line diameter, or chain pitch/gauge where applicable.
Common Mistakes

Replacement Options
Best OEM equivalent
Start with OEM references 98079-56846, 17210-ZE1-517, 16100-ZL0-W51, 28400-ZE2-013ZA and match the removed part before choosing a listing.
Named part options
Cross-check named parts such as NGK BPR6ES (spark plug), Stens 102-413 (air filter), Keihin BB62J (carburetor) against the OEM number, identity label, and dimensions.
Best for annual tune-up
Bundle spark plug, air filter when servicing the Honda GX200 at the start of the season.
Best budget kit
Use kit listings only when every included part matches this model page; cheap kits often mix correct headline parts with wrong bulbs, lines, or gaskets.
FAQ
Does this fit GX120 or GX140? GX120, GX140, GX160 are listed in the same model family. That relationship does not establish interchangeable parts; verify each OEM number, serial range, and physical detail separately.
Should I buy OEM or aftermarket parts for the Honda GX200? Use OEM when the part controls fuel metering, ignition, or safety. Aftermarket kits can be useful for routine filters, bulbs, plugs, and tune-up bundles when the OEM number and dimensions match.
How do I avoid ordering the wrong carburetor for the GX200? Match the carburetor number stamped on the removed unit, then compare linkage, choke setup, primer routing, gasket stack, and fuel-inlet direction.
What should I check before replacing fuel-system parts? Photograph the old fuel-line routing, match line diameter and filter style, and compare primer bulb size before buying a kit.
