I know Viperwolf would solve it if he was able to get near it, but since so much has changed in such a sort time I see where he is going, looking for what hasn't be swapped out via trouble shooting. Do you have the original dizzy still? I know it isn't ideal but you could swap it out (30 min job) and see what happens. In addition you could try to rule out other contributing systems like fuel & air, I think you already swapped the fuel filter right? Recent carb or other fuel system changes?
Dual points are a good upgrade but are super pain in the ass to set perfect. Looks like you just need to dump it. Kiddin, you just need to get that thing to a tech class. Or else your just gonna be dumping money in to unnessary parts
