Description
Overview:
The Insulator/Carburettor Gasket for Honda GX120K1 engines (MPN 16221-ZH8-801) is a genuine Honda OEM sealing gasket designed to sit between the carburettor and the intake side of the engine or insulator block. Made from a durable, fuel- and heat-resistant gasket material, it maintains an airtight joint to protect engine vacuum, mixture accuracy and idle stability. Correct sealing helps prevent hard starting, poor running and erratic performance. This gasket is suitable for small Honda petrol engines used in equipment such as generators, pumps and tillers, including popular models like the GX120K1 and GX160K1. It is a straightforward service item that should be renewed whenever the carburettor is removed or an air leak is suspected to keep engines running reliably.
Key Features:
- Genuine Honda part for assured compatibility and fit
- Designed to prevent air leaks for stable idle and smooth acceleration
- Fuel- and heat-resistant material suited to E5/E10 petrol environments
- Maintains correct vacuum and mixture control for efficient combustion
- Precisely cut ports for accurate alignment with carburettor and insulator
- Consistent thickness to support correct spacing and clamping load
- Helps reduce risk of rough running, surging and hard starting
- Simple to install during routine carburettor service or rebuild
- Reliable sealing performance over repeated heat cycles
- Suitable for a wide range of Honda GX-series engines
Typical Applications:
Used during carburettor removal, cleaning or replacement on Honda GX-series engines powering generators, water pumps, plate compactors, pressure washers and tillers. Common in workshop servicing to cure vacuum leaks, restore stable idle, and improve cold starts. Ideal for preventative maintenance when refitting a carburettor or insulator block.
