Here's how it works and jag sells his CDI to a couple of different people

I think this is where you can buy the real jag CDI.... I've heard nothing but good things about it but I can't afford them and I haven't had much problems with the stock CDI
You probably should be using full synthetic oil with a cold plug like a B7HS or B8HS and the highest octane fuel you can get
Do all of that and it should run better even if what's going wrong isn't what we think it is
