Was cruising fine yesterday al of a sudden my rpm's went down and my ski was running very sluggish. Took it out replaced the spark plugs and put the coils back on, turned it on and the same thing, removed the spark plugs and noticed #2 cyl plug did not get a spark or fired so I figured it was the coil and replaced it new and I still can't get my #2 spark plug to fire when i take the spark plugs back out #1 & #3 show the marks of being firing but #2 looks brand new so it wasn't the coil or plug, please can anyone help me with this. Thanks
