Description
Overview:
This Inlet Insulating Bush is a genuine Villiers spare for the B1016 carburettor used on 125cc and 150cc four-stroke industrial engines. It sits between the carburettor and the inlet to reduce heat transfer, helping to prevent vapour lock and fuel boil-off, and to maintain stable running and idle. Made from a heat‐resistant insulating material, it supports correct carburettor spacing and alignment for a reliable seal. Suited to Villiers Type 512V/515V vertical shaft engines found in a wide range of industrial and horticultural machinery. Supplied as new old stock, so light tarnishing or shelf marks may be present, but performance is unaffected. Genuine Villiers part, OEM No. 28083, for dependable fit and function with the B1016 carburettor.
Key Features:
- Genuine Villiers part (OEM No. 28083) for assured compatibility with the B1016 carburettor
- Heat-insulating bush reduces heat soak from the engine to the carburettor for improved hot running and starting
- Helps maintain mixture density and tuning stability by limiting fuel percolation
- Accurate fit for Villiers 125cc/150cc Type 512V/515V vertical shaft engines
- Supports correct carburettor spacing and gasket compression for a reliable, leak-free seal
- Durable, heat-resistant construction for long service life in industrial use
- Direct replacement; straightforward to install with standard hand tools
- New old stock: may show minor cosmetic ageing, with no impact on function
- Suitable for maintenance and restoration of vintage Villiers-powered equipment
- A practical way to protect the carburettor body from heat-related distortion over time
Typical Applications:
Used when servicing or rebuilding Villiers 125cc and 150cc industrial engines to restore proper carburettor insulation and spacing. Common in vertical‐shaft equipment where sustained running can transfer heat to the carburettor. Ideal for preventative maintenance, solving hot‐start issues, addressing poor idle caused by air leaks, and supporting accurate carburettor tuning on legacy machinery.
