The Midget is a 98cc two-cycle air cooled engine which was produced between 1931 and 1934. It is a small power unit with a bore and stroke measuring 50mm by 50mm and developed its rated 1bhp at 2,700rpm. This engine introduced a new pattern in the Villiers engine construction with its exhaust and transfer ports placed at the side of the cylinder in line with crankshaft and a retaining disk being used to prevent the gudgeon pin entering the transfer port. The cylinder and head were cast in one piece and a cast iron deflector type piston was used. Roller bearing big ends and a force fit crankpin completed the job. The cylinder was upright as usual, and petroil lubrication was used. Large numbers of these engines were used to power scythes, small lawnmowers and bracken cutters etc. Mention must be made of an unusual use of the Midget engine in the Stanley Tricycle, a standard type of tricycle which used the Midget engine to provide the rider with additional power when required. The engine shown below, was used to power the hare at a Norfolk Grey Hound Track.
