The Honda 16223-ZA0-810 Insulator Gasket is a genuine OEM component designed for EV4010, EV6010, and EVD4010 RV generators. As a direct OEM replacement, this gasket is sourced from Honda and built to the same specifications as the original, ensuring a proper seal at the carburetor insulator. Confirm your generator's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks.
Key Features
- Genuine OEM Sealing — sourced directly from Honda, this gasket delivers the correct material grade and sealing profile for the carburetor insulator junction on EV-series RV generators.
- Direct OEM Replacement — matches the original part geometry exactly, so this gasket installs without modification on EV4010, EV6010, and EVD4010 RV generators.
- Serial Number Awareness — Honda updates part supersessions at serial breaks; check your generator's serial number against the fitment table to confirm this is the right gasket for your unit.
- Leak Prevention — a deteriorated or missing insulator gasket allows air or fuel vapor to bypass the sealed interface, disrupting fuel metering and causing hard starting or rough running.
The Insulator Gasket seals the joint between the carburetor and its insulator spacer on the engine, preventing unmetered air from entering the fuel charge. A proper seal at this interface is essential for consistent fuel delivery and stable engine operation. When this gasket degrades or fails, vacuum leaks at the carburetor mount can cause erratic idling, hesitation, and difficulty maintaining a steady load — common complaints on RV generator engines that see infrequent or seasonal use.
