One final thing, and I know we're on the verge of beating this horse to death, but I just noticed that the throttle cable is not hooked to the carb at the same place as the kickdown. That's just wrong. Both should attach at the same place on the carb so they will travel the same distance. Also, where the throttle cable is attached is almost certainly incorrect, and I'd be surprised if it is able to open the carb all the way at full throttle.
