Bad switch box stator coils or power pack?? 30mariner

[Smokepole27]

So Im done trying to see what fuel issue im haveing Ive done everything. How can you determine if you have a bad power pack stator or coils? Im haveing problems with my top end missing or studdering, it runs fine until I get wot on plane. Sometimes itll run fine and others it will not some really needing to test the electrical system but dont know exactly how to do it.. I will be changing a vacum line tomorrow but pretty sure thats not the problem. How do I check these Items?By the way compression is around 110 give or take a few.

When you change the vacuum hose for the fuel pump make sure you buy hose clamps. Those stock squeeze clamps don't seal very tightly. Make sure you get em nice and tight.
