[QUOTE="rktman, post: 475031, member: 11818"] My 96 Johnson 40 2 cyl has been randomly missing/popping at upper RPMs for a while and was getting worse. I thought it was fuel problem but replacing the fuel pump, cleaning carbs, new fuel etc. did not help. I've checked compression, 157-158 psi on both cylinders. Spark looked OK but a little reddish on my cheap tester so I thought perhaps it was a CDI problem. I removed the old CDI and found a crushed white wire between the unit and the mounting bracket. I installed new CDI brand CDI unit per the instructions. Started it up, ran 2-3 seconds, then died and will not restart, not even with the old CDI. I replaced the primary coil with a spare, same result. Same reddish spark, new plugs, still no start. Any suggestions? [/QUOTE]
