I had to pull my blower off today to remove my J&S so i figured I would take a peek at my plugs. The numbers represent what cylinder they came out of, I only pulled 3. From the looks of it the boot on cylinder one got some water in it hence the corrosion. The plugs 1 & 3 look good but not2, I don't understand why the front bank would burn differently than the rear.
