I think you got a bargain from your info. Glad to hear that the c5 will work since I also have an 84 engine that might need that in the future. The stator may be dark due to the fact that they started allowing oil to circulate through the stator housing in 84 but it also could just be burnt up, just have to test it. They had major stator problems in 84 and factory recall on them, if that particular engine received a new stator the rear case should have some punch marks visible from the left side. Can't remember if there in a straight line or diamond shape, something Honda came up with to ID whether the recall was done or not. The stator is also suppose to be 350 volt (29 amp) but I can't remember if that occurred in 84 or took place in the 85-87 when they changed the rear cover. Congrats.
