93 Sunsport High Idle After Cruise

[Moor]

you should have an electric choke on your carb, i'd start there and make sure the choke isn't sticking, causing a high idle. It happened to me once on my old ski nautique, it can be adjusted with a flat blade screw driver.
also check to make sure all of the throttle linkage, throttle plates/shaft and the cable isnt sticky and moves free through out the entire operating range. It may me time for a carb rebuilt also. Definately sounds carb related to me.

what rpm does it idle at when it idles normally?

Normal idle seems ok. Maybe 800 or so. Then when it sticks it goes up to 2-3000. I was thinking about the electronic choke and wondering if that could be it, since the problem does seem to be related to something electrical (since it goes away when you stop and restart.) Was also thinking about doing a carb rebuild as well. Are these fairly easy to rebuild or am I better off having a professional do it?

You can try to unhook the 12v power wire that attaches to the choke (the only wire on it) and unhook the choke linkage or wire it open, then see if your still getting a high idle. if not, then your problem is more than likely a misadjusted or bad choke.

I've rebuilt my fair share of carbs. If your careful, organized and take your time, its not very difficult. There's small pieces that are lost easily. Other than that its just cleaning and replacing gaskets for the most part.
If your somewhat mechanically inclined then i'd say give it a try
