2110 Engine Set Up Questions

38 choke tubes. 155/160 main x 195 air x 55/60 idle and pump. F11 tubes. Bosch WR7CC plugs, the WR7DC extended nose water cooled plug (boxers)works well also. the usual 32* max advance applies.
120 cam and 42mm valves/1.25 rockers, will power to 6800, engine will be safe at 7000. plug gaps at .030" is good. all the jetting is based on safe rich UK sea level, so local corrections will apply if at altitude.
