I can say that the "screw in portion" that "seats" the needle is not correct (yet it is brand new!) because you can pull the needle out of the "seat" completely. Should it be seated in securely, or is it supposed to fall right out if you turn it upside down? It's very hard for me to describe this stuff in words, so perhaps I need to take photographs.

I appreciate the responses. you guys are very helpful.

Thanks
