Any insight on getting the metering springs and a new needle for a WDA 31 a. Most of the full rebuild kits are out of stock. I am flooding the base of my panther with a few pulls I am guessing the needle is bad, it has a rubber tip on it . I am thinking the seat is pressed in and not serviceable am I correct? I have not checked the needle arm clearance yet, but would prefer to replace the needle before I try it. I am missing one of the metering springs.
