16100-Z8B-911 Carburetor with Air Filter Gaskets Spark Plug for Honda GCV190LA N5B GCV190LA N5BR GCV190LA G5AP GCV190LA G5B GCV190LA G5BR Lawn Mower

What It Is

This is a complete replacement carburetor kit for Honda GCV190LA series engines, commonly used on push mowers. It includes the carburetor, air filter, gaskets, and a spark plug—everything needed to fix starting or running issues caused by fuel system problems.

Fitment & Compatibility

• Engine models: Honda GCV190LA N5B, N5BR, G5AP, G5B, G5BR. Check the engine model number stamped on the blower housing (not the mower deck).
• Deck size: Fits any mower with a GCV190LA engine—deck size doesn’t matter.
• OEM vs aftermarket: This is an aftermarket kit, not genuine Honda. It may require minor adjustment (e.g., idle speed screw) after install.
• What to verify: Ensure your engine uses the same bolt pattern (two studs, 60mm center-to-center) and throttle linkage style. Compare the old carburetor’s mounting flange and fuel line diameter (5/16” typical).
• Spark plug: The included plug (usually a BPR6ES or equivalent) fits the GCV190LA. Confirm gap is set to 0.028-0.031 inches before installing.

Key Things to Know

• Quality: Aftermarket carburetors can vary. Most users report it works well, but a few note the float or gaskets are slightly off. Inspect all parts before install.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, fuel line, and throttle cable. Clean the old gasket surface and check for debris in the fuel tank.
• Common gotcha: The supplied spark plug may be pre-gapped incorrectly—always check and adjust. Also, the air filter may be thinner than OEM; it works but replace with a Honda filter later for better dust protection.
• Tuning: After installation, the engine may need idle speed adjustment (turn the screw on the carburetor linkage). Start with 1.5 turns out from lightly seated for the mixture screw if adjustable.

Should You Buy It

Buy this if you have a Honda GCV190LA engine mower that’s hard to start, runs rough, or won’t stay running—and you want a budget-friendly, all-in-one fix. It’s a solid value for DIYers who don’t mind minor adjustments. Avoid if you prefer OEM parts for long-term reliability or your engine has unique linkage variations.
