So my carbs were leaking, fouled plugs, and rough idle. I was informed that my floats were probably stuck so I took out the carbs and cleaned them out. Carbs are now assembled back and the bike starts and no leak so far but it idles high at about 3000rpm. I attempted to adjust the idle screw but it didn't do anything. Any thoughts? Would adjusting the mixture screw and then synchronizing the carbs fix the problem. Thoughts and ideas are greatly appreciated.
