Description
Overview:
The Villiers MK40 Replacement Valve Spring - EM140 is a genuine Villiers part designed to restore correct valve operation in classic Villiers engines. Made from durable spring steel, this helical coil spring provides the tension needed to close the valve cleanly after each cam cycle, helping to maintain compression, timing, and smooth running. It is intended for use on Villiers MK40 and EM140 engines commonly found in small plant, garden machinery, and stationary equipment. As unused old stock, the spring may show light tarnishing from age, which does not affect function. This OEM EM140 valve spring provides a precise fit to the original specification for reliable service during routine maintenance or full engine rebuilds.
Key Features:
- Genuine Villiers part for assured compatibility and fit (OEM EM140)
- Durable spring steel construction for long service life
- Maintains valve seating, timing stability, and engine efficiency
- Consistent spring rate to resist valve float and misfire under load
- Heat- and fatigue-resistant for repeated thermal cycles
- Suitable as a direct replacement for worn or fractured valve springs
- Unused vintage stock; cosmetic tarnish may be present without affecting performance
- Straightforward to install with standard engine service tools
- Supports easier starting, smoother idle, and more reliable running
- Correct for classic Villiers MK40/EM140 applications where OEM accuracy matters
Typical Applications:
Used during servicing or rebuilding of Villiers MK40/EM140 engines in mowers, stationary machinery, compact construction or garden equipment. Ideal when addressing loss of compression, hard starting, backfiring, or unstable idle caused by a weak or broken valve spring.
