The Villiers Mk.7 was a neat and compact four-cycle, side valve engine, with few moving parts. The engine was fitted with the Villiers flywheel magneto, with the engine cooling fan mounted on the outside of the flywheel. Speed was controlled by a simple air-vane governor. Most of the parts were made in-house.

The engine had a 50mm bore and a 38mm stroke. The total swept volume was 74.63 c.c. and the engine could deliver 1.3 b.h.p. at 3,600 r.p.m. It was air-cooled by fan and cowling. The engine was fitted with a Villiers B10 carburettor as standard, the air filter being of the oil-wetted gauze type or oil bath. The capacity of the fuel tank was 2 pints. Lubrication is by “splash”.  The oil sump held one pint. It was fitted with a Lodge BN (14 mm) spark plug.

The Mk.7 engine was commonly used to power motor mowers.

This engine was fitted to a lawn mower.  It was given a clean up, a new exhaust and mounted on a trolley.  The paint work is original colour. This engine will run, vibration free, all day at shows.
