Superjet loss of spark when revved up.

[Josh Watson]

I have a 06 superjet that is all stock, it was running fine and then it started running like crap, I got it home and figured it was ignition. The ski will run on and run but runs like crap when you give it throttle, I put a spark tester on it and the spark gets super weak and almost where you can’t see it when you rev it up. Any ideas?

Pull the plug boots, take some needle nose pliers and tug on the wire, if they pull out out, cut the wires back the length of the longest strand that pulled loose, cut and repeat. Most likely you have broken wires, it cranks fine, you rev up and the vibrations cause the spark to get weaker. Either that or your stator is going out.
