Outboard Misfire - HELP?

[Brad Harshman]

Here's a video of it running.  It does this all the time, but mostly on idle.  When idling it usually kills the motor.  When at cruising speed, it very noticeable.   

I cleaned the plugs, they were a little damp and had black carbon on them.  Cleaned regapped and reimstalled. Still misfires.  I religiously use seafoam. 

Any and all help is greatly appreciated.

Could be several things but it sounds to me like you may need to adjust your air mixture screws on the front of your carbs.
