I am looking into the feasibility of boring/ honing the throttle plate ( the cast iron throttle body with the butterflies ) on a Holley "94" "8BA" carb to the "EGC" 1 1/16 bore size. Has anyone done this with any success? The reason I ask, is because these EGC carbs are hard to come by up here, and I have a couple of them that the bases are rusted up, and the mixture screws are broken off in them. we have several of the "8BA" carbs that have mangled tops, but the rest of the carb, including the bases are good. Thought that maybe I could make a good carb out of the bad "EGC" if the "8BA" bases can be bored, and not have any problems with any of the other orifices that are bored at an angle into the carb, such as the idle circuits, etc. any body tried this? any success? any ideas, or comments. just trying to make something good out of junk.----- Jim
