2000 GTX 947 Fresh rebuilt engine, have already broke it in, but I seems to have an issue with either the carbs or an air leak. Problem; Set idle at 1400 RPM in water & adjusted Low & High screws, if you touch the throttle on the way out of the no wake zone the RPM will rise to as much as 2200 RPM & won't go back down unless you quickly punch it a couple of times then it will drop to 1600 RPM, I adjusted the idle screw again & it still does the higher RPM if you so much as touch the throttle. It has a little hesitation at first when you punch it but seems to run fine after that except for the idling. Also, when I pull it out of the water & rev it up to get the water out of the pump etc. it revs down really really slow.
