I am having a problem getting my 22zx to idle. It is a 454 carbed model. When I first start it (after warm up) it runs great. Idles around the marina with no problems. Once I run the boat for any time at speed then slow down it runs rough like it is missing. Let it sit for an hour or so and it runs great again. When I am ideling around the RPM's are about 500 when i bump the throttle it dosent move then all of a sudden the idel will jump to about 1000 rpms. I cannot get it to settle anywhere in between 500 and 1000.The boat pulls hard and I have lost no speed or rpm on the top end. Here is what I have tied so far. New fuel filter/seperator, New plugs, cap and rotor, treated fuel for water, hosed the carb with carb cleaner (thought it was the choke sticking), and checked for vacume leaks. I do not know anything about a q-jet carb and I am afraid that is what it is. Does anyoue have any other suggestions?

Thanks
Garland
