The Honda 16134-Z6L-801 Adjusting Screw Cap is a genuine OEM replacement designed for GX630, GX660, and GX690 horizontal shaft engines, GXV630, GXV660, and GXV690 vertical shaft engines, and the EB10000 generator. As a direct Honda OEM component, this cap is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation. Because Honda supersedes parts at serial number breaks, verify your unit's serial number against the fitment table before ordering to confirm part number 16134-Z6L-801 is the right match for your machine.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this cap meets the original design specification for correct fit and function on covered models.
- Broad Fitment — covers GX630, GX660, and GX690 horizontal shaft engines; GXV630, GXV660, and GXV690 vertical shaft engines; and the EB10000 generator, including both horizontal and vertical crankshaft variants in Honda's large-displacement lineup.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so always cross-check your machine's serial number against the fitment table to confirm this is the correct cap for your specific unit.
- Protects Adjustment Integrity — keeps the adjusting screw sealed and free from contamination, maintaining consistent fuel metering and preventing unwanted adjustment drift.
The Adjusting Screw Cap fits over the mixture or idle adjusting screw on the carburetor, sealing the tip of the screw from dirt, debris, and accidental disturbance. This small cap plays an important role in keeping the carburetor's fuel and air mixture calibration stable — once a technician sets the screw to the correct position, the cap holds that setting in place and protects the screw's fine threads and taper from wear. When the cap is missing, cracked, or improperly seated, the exposed screw is vulnerable to contamination and unintended movement, which can cause rough idling, poor throttle response, or hard starting across the engines and equipment it serves.
