I was not referring to the hole in the carb, I am assuming the pump has a pressure sensing hole, otherwise it could never function as a pressure regulator. It is that hole I was referring to, and the reason I was thinking about it, was because some people report the engine is running OK, others are reporting it is not, and that pump/regulator is subject to "owners view to correct installation" so it is possible, that results vary from owner to owner because of pressure fluctuations on this hole, caused by differences in installing it.
