Description
Overview:
This Genuine Honda carburettor insulator is a heat-resistant spacer that sits between the cylinder head and carburettor on Honda GX340 and GX390 engines. Made from a durable, heat-insulating composite (black phenolic-style material), it reduces heat soak into the carburettor to help maintain stable fuel vapourisation and smooth running. By limiting heat transfer, it helps prevent hot-start issues and keeps the mixture consistent under load. It is a direct replacement for OEM part numbers 16211-ZF6-000 and 16211ZF6000, ensuring correct alignment and sealing. Commonly found on engines powering generators, pumps, plate compactors, pressure washers, and other construction and garden machinery, this insulator is a reliable fix when servicing the intake system or addressing erratic idle and overheating-related fuelling problems.
Key Features:
- Genuine Honda OEM part for assured compatibility and performance (MPN 16211-ZF6-000 / 16211ZF6000)
- Heat-insulating composite reduces carburettor temperature and vapour lock risk
- Direct-fit replacement for GX340 and GX390 intake assembly with correct port and stud spacing
- Helps stabilise idle and throttle response by maintaining consistent fuel atomisation
- Supports easier hot restarts and improved reliability under heavy loads
- Durable, warp-resistant material for long service life in high-temperature environments
- Smooth sealing faces designed to work with standard Honda gaskets (not included)
- Suitable for engines used in generators, pumps, compactors, and pressure washers
- Straightforward installation with standard hand tools; no modification required
- Honda Genuine Part status for quality assurance and dependable fit
Typical Applications:
Used during carburettor replacement or service on GX340/GX390 engines in site generators, water pumps, plate compactors, pressure washers, and similar equipment. Ideal when resolving hot-start issues, fuel percolation, or inconsistent running due to heat soak. Common maintenance item after overheating events or when the original insulator is cracked, warped, or leaking.
