Thanks to all. This machine was definitely before the age of plastics. Built like a brick ####house! I agree a carby problem -probably a wrong oil/petrol mix. The 50:1 mix in the PDF sounds more modern. Many old machines used a much richer mix -- 1:8, 1:16 or 1:20. If I can find the points, would, like my old Bantam motorbike, fully open might be 15 thou and 7 degrees BTDC be 1.5 thou. Would that be a starting point to get it going? Cheers.
