[QUOTE="hogslayer, post: 110938, member: 1263"] Does it seem like it is not idling because it is not getting enough fuel or because it is flooding out. After it dies how hard is it to start again? Do you have to open the fast idle all the way up to start it? I'm guessing it is most likely the idle circuits in your carbs. They are very small orifices and mixed gas will very quickly varnish up and clog or restrict them if the motor has sat for even a couple months some times. With the muffs on in your driveway you don't have any backpressure and air can flow very easily through the engine. The more air flowing through your carb the more fuel getting sucked out the idle passage into the intake through venturi effect giving you enough to idle good. Less air flow through the engine while in the water due to backpressure and you do not have quite enough fuel getting sucked in at idle. You probably don't need a kit and can get by with just cleaning them. As stated you can soak it in carb cleaner, stanasol or even diesel fuel works very well. Take a can of aerosol carb cleaner with the red spout thing and blast it through the passages and then blow them out with compressed air and you should be good to go. Sometimes the carb needs to be adjusted throughout the season on some motors. I had a motor that would idle beautifully in the spring in the cold dense air but would flood out really bad at idle during the summer when it was hot. I had to adjust it to give it more fuel in the spring and turn it back down in the summer. Carb issues can be a pain, but usually pretty easy to remedy. Good luck [/QUOTE]
