The Honda 16016-ZA8-003 Pilot Screw Set is a genuine OEM Pilot Screw Set designed for Honda EM650 and EX650 generators and the EX350 inverter generator. As a direct Honda OEM component, this set delivers the exact tolerances and thread specifications the carburetor demands for stable idle and clean low-speed fuel delivery. Confirm your model and serial number against the fitment table before ordering, as Honda supersedes carburetor hardware at serial breaks.
Key Features
- OEM Fuel Metering Accuracy — manufactured to Honda's exact taper and thread specification, ensuring the pilot circuit meters fuel at the correct mixture ratio for stable idle
- Direct Carburetor Replacement — this set installs directly into the pilot circuit of the carburetor with no modification, restoring the factory idle mixture adjustment that worn or damaged screws can no longer hold
- Broad Generator Fitment — covers the EM650 and EX650 generators and the EX350 inverter generator; verify your serial number against the fitment table to confirm the correct application
- Idle Stability and Low-Speed Response — a correctly seated pilot screw is what allows the carburetor to sustain a steady idle; a worn or improperly seated screw causes rough idling, stalling, and poor low-speed throttle response
The pilot screw is the fine-adjustment needle in the carburetor's pilot circuit, regulating the air-fuel mixture at idle and low engine speeds. When it is worn, damaged, or out of adjustment, the engine struggles to hold a steady idle and may stall under light load. Replacing the pilot screw set with a genuine Honda part restores precise mixture control, allowing the generator to run smoothly and respond cleanly as load is applied.
