Well Gray, the solvent probably has some petroleum base in it and could lead to reduced sparking. Wipe that sucker squeeky clean before you strike it.
As for the frizzen being loose, it should flop open but if you flint is adjusted properly it should open completely as you said it does. Also if your flint isn't square to the frizzen it probably will chip a little but after a few firings it shoud square itself up (self knapping if you will),
