Description
Overview:
The BSA Engine Valve - Villiers Part - 86 6526 is a vintage, unused old stock metal valve for small petrol engines commonly found in construction and garden machinery. Built to regulate the opening and closing of the intake or exhaust port, it helps control the air-fuel mixture and exhaust flow for efficient combustion, reliable starting, and steady running. Made from durable metal suitable for high temperatures and repetitive cycling, this valve is intended for selected Villiers-powered machines such as lawn mowers, rotavators, stationary engines, pumps, generators, and light site equipment. As old stock, it may show light tarnishing or storage marks, but it remains to original specification and is a practical choice for restoring period-correct performance in older engines that require a like-for-like replacement part.
Key Features:
- Unused old stock (NOS) part made to original specification
- Durable metal construction designed to withstand heat, wear, and repeated operation
- Supports correct valve timing and sealing for compression and smooth running
- Suitable as an intake or exhaust valve depending on the engine variant
- Ideal for restoring vintage Villiers-powered machinery and stationary engines
- Straightforward to install during a top-end rebuild with standard workshop tools
- Can be lapped to the seat to achieve a gas-tight seal where required
- Helps improve starting, idle quality, and overall engine efficiency
- Cosmetic tarnish or storage marks may be present but do not affect function
Typical Applications:
Used during engine overhauls, top-end rebuilds, and maintenance on vintage Villiers engines in lawn mowers, cultivators/rotavators, water pumps, generators, and small construction plant such as site mixers. Suitable for enthusiasts, restorers, and workshops maintaining legacy equipment where original-style components are preferred.
