I have an '84 FJ60 pretty much completely stock with all emissions intact. I recently installed a rebuilt engine, and while it was out, I had the carb rebuilt by a shop recommended by the guy that helped me with the engine install. My truck runs great, but I can't get it to idle smoothly. That suggested a vacuum leak, and with a can of carb cleaner, I was able to determine that there was leakage between the shaft and bushing for the primary butterfly. I am going to go back to the shop that rebuilt the carb, but I want to get a little smarter first. Does a routine rebuild normally include checking the bushings and replacing if necessary? Do rebuild kits normally include these bushings? In any case, is there any place for me to get new bushings, or do I have to get the micrometer out and get new ones made? Thanks for any help ! ! !
