I have gone through them, cleaned, there are all composit gaskets now, I will pull it apart tonight check it all again, see whats the real problem, and the vac. gauge was very quick on its movement like 4 times a second fast. So maybee the valves? I will try to pull the valve covers to see if I have a broken valve spring, just dont know why its always been so rich never has been lean since I have had this carb,
