Cliff,
my carb is #7029268WF.
Do you sell the needle and seat set with the Closed Seat for this carb?
I have a fuel drain back problem and I am already doing the [leave the metal hook off the float deal] and the well plugs are sealed.
I only have this problem after 2 days or more with the car sitting.
I remember back in the old days [1970's-1980's] that the Q-Jet had the incarb fuel filter [paper] that had a 1 way spring loaded valve in it.
Were those any good?
