2001 Johnson 225 cylinder not firing.

[KB2DEM]

One cylinder is not firing. Have 100 plus compression on all 6 cylinders. Have good blue spark while cranking and fuel in cylinder. Pulled plug out it's all carboned up. Disassembled carb and cleaned out. All plugs are new. Is it possible there is no spark while running. I also swapped coils with a cylinder that is firing.
Thanks for the help.

Ignition components can look good and still be an issue. When was the last time the rotor, cap and wires were replaced?

Sure you did correct carb??? This motor has a X flow intake so looking at carbs the right side feeds left bank and vice versa

?-----There is no rotor or distributor cap on this motor!

X flow makes sense, I will check the opposite carb. Thanks

Problem solved. Timing was way out of wack. Found a sheared key on the flywheel.

Thanks

So you replaced the flywheel or welded on a new key?

Just replaced the key and torqued the flywheel to spec.
