I need a replacement ? Is there anything I need to know/be aware before remove the filter ? :-)
The biggest danger is in putting the fitting back into the carb body - steel fitting into the pot metal body, and very easy to cross thread. You may get lucky and fix your drain back problem with a new filter/check valve, but the QJ's were known to leak down through the plugs in the bottom of the float bowl, too. See the link I gave you earlier, and scroll down to the "known troubles - leaking plugs".
