ok.. im up to speed.
I came across one reed block that was sorta stuck on and i had to be careful not to tear the blocks rubber seal when prying it off.. but most times it should pop right off.
Permatex 2 will provide an excellent seal without any risk of adhesion and damaging gaskets or whatever when disassembling parts.
Good luck with the other carb.. you have a new float needle which is great... I'd probably install it regardless during a quick examination of the 2nd carb.
