I polished the points and cleaned them with acetone but still just the bottom cylinder has spark. The coils are all cracked and the coating is coming off is why I thought I should replace them. Carb is all apart and soaking now and I think I managed to save the base gasket because I cant find another. Am I right in the parts list I need, 18-5156 points, 18-5181 coil and 18-5199 for the condenser? Parts seem to be hard to find for this but I am trying! Thanks, Jim
