I think you really need to do a little more checking before you just start throwing parts at it. You said compression was good but did you test it or you just think it is good? Need to start at the beginning and actually figure out what is causing your problem. First thing to do is check compression and see what the actual number is, next thing to do is pull both carbs and check your reeds and make sure they are all good. Then ohm out your stator and make sure it is bad before you throw a 40.00 ebay stator at it and still have a problem. Check those things then that will us the info needed to really point you in the right direction.
