number 4 probably means the number four plug, possibly in the firing order, or one of the sides. in any case, depending on what is wrong with he cdi, and i am not saying that is the problem, but it can still crank even if the cdi is the problem, i know this from experience. unfortunately, the only way to find out if the cdi is bad is to either rule everything else out, or get one that is known to work, and test it out. make sure you check all the fuses, make sure the carbs are getting fuel, and that all the plugs are firing, if you get firing at the plugs, and the carbs are getting feul, you should be good to go. this will mean getting a running fuel pump first.
I did that.
