The Ivy two-stroke makes a speciality of working under heavy loads, and has demonstrated its capabilities publicly on more than one occasion of late. In its general layout, the engine is of the standard three-port type with a release valve opening into the exhaust pipe. From the drip feed lubricator two pipes are taken, one conveying oil to the left-hand side of the cylinder, so that it registers with the gudgeon pin at the bottom of the stroke, the other feeding a trough at the top of the crank case, from which the oil runs down special passages to the main bearings. Chain and belt transmission is fitted for solo work, and all-chain for use with the sidecar. The dropped top tube and sloping tank are distinctive Ivy features.
2½ h.p.; 64x70 mm. (224 c.c.); single-cylinder two-stroke; Amac carburetter; chain-driven magneto; two-speed gear; chain-belt drive; Dunlop 26x2¼ in. tyres. Price £73.
Except for the smaller engine, this machine is almost exactly similar to the 3 h.p. In both cases the front down tube is double, a tube being taken down on each side of the exhaust pipe. The lady's model is especially neat, and is provided with a semi-dropped frame, one gallon tank, and a carefully protected belt.
