Thank you Scott & RB,
I have been reading his site for years, he is the "GL Guru" but being an Amateur Wrench I still can't understand a couple of things. I'm hoping he goes into more detail for this inexperienced fixer. Thank you for your response.
the needle has a spring on it too, you want to close the needle valve but not depress the spring. thus the reason to stand the carbs on end , to let them close lightly , without the weight of the floats pressing the spring.
the float"halfs" need to be parrellel or flat to each other.if not just bend then flat again.( in other words when they are on the card and the pin is inboth black float parts should lay the same level, that's all.
