[QUOTE="Robert48, post: 454610, member: 23401"] Okay, after cleaning all connections and performing all recommended swaps I have isolated the problem to the bottom cylinder. It seems to be getting intermittent spark. At first pulling the lower spark plug wire had no effect on how the motor ran. When demonstrating this for a friend I started getting spark. I could hear the arc (snap) as the wire neared the plug and the motor would almost die with plug wire removed. Back to the lake, still only running on one cylinder under load and could not reproduce intermittent spark. I suppose it is possible I got a defective power pack. I will put on the old power pack and test that on the next lake trip. I am still unsure if I should just go ahead and replace the lower coil. Thoughts? [/QUOTE]
