Description
Overview:
The Carburettor Insulator Gasket for Honda GX340 engines is a genuine Honda component that seals the intake joint to keep your engine running efficiently. Made from a fuel‐ and heat‐resistant composite gasket material, it is cut to the correct OEM profile to provide an airtight seal between the carburettor/insulator stack and the engine intake. This helps prevent unmetered air leaks that cause poor starting, unstable idle, and loss of power. Supplied to replace OEM number 16221-ZE3-800, it offers a direct, no‐modification fit for common GX340 variants such as the GX340 and GX340K1 used across construction and garden equipment including generators, water pumps, and pressure washers. A dependable choice for routine servicing, carburettor rebuilds, or restoring factory performance.
Key Features:
- Genuine Honda part for the GX340 series for exact fit and compatibility
- Airtight seal at the intake joint to prevent air leaks and maintain correct fuel mixture
- Helps restore smooth idle, reliable starting, and consistent power output
- Durable, fuel‐ and heat‐resistant composite for long service life under engine temperatures
- Precisely punched port and bolt holes align with the OEM insulator and carburettor
- Direct replacement for OEM No. 16221-ZE3-800; no trimming or sealants typically required
- Suitable for scheduled maintenance or carburettor overhaul tasks
- Supports efficient combustion, helping reduce hesitation and rough running
Typical Applications:
Used during intake system maintenance or carburettor removal/refit on Honda GX340 engines powering generators, water pumps, pressure washers, compaction equipment, and other construction or garden machinery. Ideal when addressing vacuum leaks, erratic idle, or after cleaning/rebuilding the carburettor to restore a reliable seal.
