It seems that even brand new carbs when setting after running they internally leak. I have had rebuilt and brand new ones and all of them leak internally. Is it the gas? Perhaps something else. I have rebuilt carbs for over four decades and still running into the same problem. Starts right up first thing then when set, it takes several engine turns to restart the engine. Any ideas? Frustrating! Do I need a fuel pressure regulator or adjust the floats again. I live at 1300' above sea level.
