I bought this machine second hand here in West Australia. It goes well, is a great machine , but the governor cuts in and out as the machine idles. I would like to get a book on the engine mechanics so that I may fix the problem . I have the Operating Manual , but not the Engine Manual. Could you supply me with one, oe even email me the complete manual by email. Would be so gratefull if you could help me. kindest regards, Paul Martin.
