The power unit (2) is flexibly mounted (a,b,c) on the transmission unit. Cooling air from a fan mounted on the end of the crankshaft (17) is circulated around the cylinder head (13) and the cylinder barrel. Cooling air passes round the crank-case of the engine, inside the transmission casing (20) and escapes through the orifices (73) and (63). |
