Dear David, I am restoring a JAP S80 and have found parts for this mower from Frank Jarky in Bankstown, Sydney. You can contact him on 02 97094923. Can you help me I need a chasis for my JAP as the engine I had did not come with a chasis. It is a rotary mower. Bore 46mm. Yours sincerely, Paul Rovali 02 91504434
