I'm looking for some help on how to adjust the idle on my 1999 seadoo GTX. It idles at about 800 RPM's and seems on the edge of stalling. It tends to foul spark plugs frequently which I believe is a result of this. I'm forced to go out of my cove at idle for about 5 minutes because of a no wake zone. Any help on how I can adjust the idle up would be great.
