Hi Roger, Managed to get a few minutes in the garage! Just to be clear, by pump rods I assume you mean the accelerator valve which is held in place by a small plate. I have taken both of these out and they seem to be clean, and moving freely. The same goes for the pump inlet and outlet valves. However, you talk about the rods 'sitting high'. With the throttle closed they are virtually sitting on the carb body. The front carb pump is only about 1mm up, and the rear about 1.5mm. When the throttle is opened, the rod falls by that minute amount, but that is all. How high would you expect the rods to be proud of the body? Regards Terry
