What I did was to get a sheet of .015 Teflon sheet from McMaster Carr.
I cut 2 pieces about 1" long and 1/2" wide and work them into the counterbores on re assembly.
Works real well and when a rareish carb is being used, it could save these parts from a miss drilled oversized bushing hole.
Great information for the board and to give access to the write up. Here is the link: http://rmcavoy.freeshell.org/Q_Jet_bushings.html
