Engine
John Allen and Sons used a number of engine types, the most common being a Villiers two-stroke with magneto ignition and rope start. The engines may fail to start because of ignition problems. The spark should occur when the piston is 3/16 of an inch before top dead centre (TDC) on all Villiers engines except for the Villiers Mk. 11c which should spark 5/32" before TDC.
