Just received my 4600 mile 1977 CB400F. The bike is all original and I mean all original. From tires to mirrors. It is in about 6 boxes. The previous owner took it apart and then never had the time to put it together. I have started to assemble it. Got the front end and rear on. But as I was taking an inventory of the parts, I noticed it has nut, bolts, and a assortment of fasteners missing. Then I took apart the carbs to check them because the slides were not moving. The carbs had a layer of varnish in them. Cleaned them out, but in the process of removing the float on one carb the pin got stock and the bracket arms that holds it snapped Any suggestions on repair would be appreciated! This looks like a cool and fun sight. Looking forward to being on board!!
