carburetor rebuild epoxy location?

[Joseph K.]

I am rebuilding a Rodchester 7029207 for a SB and have a question on the location of where the epoxy should be placed and what brand of epoxy should be use. Also How should the area be cleaned prior to placing the epoxy. Thanks Joe

Re: carburetor rebuild epoxy location?

The Quadrajet's bowl had pressed-in plugs used to seal holes left after drilling fuel passages during the manufacturing of the carburetor. These plugs in the Q-jet sometimes leaked fuel causing; (a) a cold engine being hard to start, (b) erratic idling, (c) poor fuel mileage, and (d) excessive emissions. Many Quadrajets have their fuel bowl plugs sealed with epoxy (I used JB Weld) when rebuilt to prevent leaks. Clean the surface with lacquer thinner, scrub the surface scotch bright or sand paper, clean the surface again, then apply the epoxy. Attached is a picture of the plugs that typically leak on Q-Jets.
