Description
Overview:
This is a Genuine Villiers piston assembly in +0.020 inch oversize (+0.508 mm), made for the Villiers MK 16H engine. Manufactured in high-quality aluminium alloy for strength with low weight, it restores correct piston-to-bore clearance after a rebore, helping to recover compression, performance, and starting reliability on vintage small engines. Supplied as an oversize assembly to suit a cylinder that has been machined 0.020 in (0.508 mm) over standard. OEM reference: SSA34/020. Ideal for maintaining originality on period machinery powered by Villiers industrial engines. Please note: this is unused old stock (vintage) and may show superficial tarnishing, light storage marks, or dust from long-term storage; this does not affect the part's function once cleaned and installed.
