Boiler fed by injector and mechnical pump with bypass. Single  cylinder, slide valve actuated by Stephenson's valve gear. Two speed  transmission with winch behind nearside rear wheel and tender-mounted fairleads.\u003c\/p\u003e  \u003cp\u003eAs with all kit-build engines, the parts benefit considerably from  sympathetic fettling on assembly and careful checking at all stages for free  running.
