Description
Overview:
This Carburettor Insulator (Honda part 16211-ZL8-000) is a Genuine Honda OEM component for small petrol engines in the GC/GCV/GSV family. It sits between the cylinder head and the carburettor to act as a thermal barrier, reducing heat transfer and helping to keep fuel temperature stable. The insulator is a heat-resistant composite (phenolic-type) block designed for long service in outdoor power equipment. By limiting heat soak, it supports consistent mixture, smoother running and reliable restarts in tools such as walk‐behind mowers and compact machinery driven by Honda engines like the GC160 and GCV160. It replaces worn or heat-damaged spacers with a precise, direct-fit part built to Honda's specification for sealing faces and port alignment.
Key Features:
- Genuine Honda OEM part for assured fit and compatibility (16211-ZL8-000)
- Heat-resistant composite insulator reduces heat soak into the carburettor
- Helps maintain stable idle and running by keeping fuel/air mixture consistent
- Precise moulding for correct port alignment and reliable sealing surfaces
- Direct replacement; installs between head and carb using existing hardware
- Durable, fuel- and heat-resistant construction for long service life
- Supports reliable hot restarts and reduces risk of vapour lock in warm conditions
- Widely used across Honda GC, GCV and GSV 135/160/190 series engines
Typical Applications:
Used on Honda-powered lawnmowers (HRG/HRX/HRD/HRB ranges), as well as compact equipment such as pressure washers, small generators, tillers and pumps built around GC, GCV and GSV engines. Ideal when refitting the carburettor, resolving heat-related running issues, or restoring OEM performance during routine servicing.
Also known as:
Carburettor spacer, carb spacer block, inlet insulator, intake manifold insulator, heat isolator block, carb isolator, carb heat block.
