evening all.........yes i`ve been here on and off keeping up to date with the major surgery thats in progress :lol  only question i have is, why when you filled up the comb / chambers with fuel that partly leaked out after a short while, did you instantly suspect the head gasket? reason i ask is............if the valves are all nicely seated ( closed) and the `crush` washer on the plugs are in good shape, then for all intent and purposes that chamber should be water / fuel tight. am i correct? if `fluid` is leaking somehow, then its seeping past a valve or dicky plug washer...........so where does the head gasket come into all this? bear in mind the head has been upside-down during this test? still sticking with fuelly / carbs issue........sowwy ! :rolleyes
