I took my carbs off and cleaned them out real well. Engine runs good. The only problem I am having is that once in a while when idling the engine will stall. I can either be just idling or coming from high speed. It doesn't stall all the time and starts right back up when it does. can anybody help?

Sounds like idle speed is set just a tad too low. My 2000 used to do that, and I adjusted the needle on the carbs and took care of it.

it's idling about 750 rpm in the water. I backed the slow speed out on each carb 1/2 turn and it got worse, so I turned them back in. I am new at this so I guess it wouldn't hurt if someone could tell me the proper way to set the carbs
