1995 200 Johnson venon running rough

[oceanrunner0000]

This engine sat-up for 8months. I replaced the stator and power pack because it wouldn't start. Afterward the replacement, the motor started but would run rough and cut off. When its cold(first start-up) it would idle OK,but not perfect. Boat Mechanic said the carbs need replacing. I purchased new/used carbs. It ran fine for about thirty minutes continuously. I cut the motor off, and restarted it then it got sluggish. I noticed the temperature rising on the right head(standing behind motor) I cut it off and ran h2o directly by passing the h2o pump on lower unit. I pulled the spark plugs and discovered, standing behind motor, the second cylinder from top on left , the spark plug had dry carbon on it. The rest of the plugs were wet. In process of during a compress test on each cylinder.
In the meantime, I replaced the stator,power pack,plugs,rebuilt and replaced carbs(not warped) , and fuel. Can someone stir me in the right direction. The number two plug concerns me. What is the problem?

I found out the problem. What had happened, when i replaced the power pack wires, i replaced them according to the length. However, the second one (wire) to coil was wrong. I switched them(the top one and the second one). To verify the correction before starting, its color coded. The top one is orange/blue,second one..just plain orange,and last one to coil orange/green. The other side(right) was corrected. This explain the carbon on the second plug on the left side and the right side running hot. Misfiring. Thanks any way. The pulling the spark plugs help me solve the problem. Thanks for those who shared their solving problems....it helped me!

OMC back in those days had the wrong color codes on the length of the wires. Glad you found it. You're not the first one to get burned on this.
