I recently purchased a '96 Sea Doo GTI Bombardier that had been setting for several months. It starts and will rev up out of the water. In the water, you really have to work with the throttle to get it going. Once going it runs good at high speed. I was wondering if the low speed jets need to be adjusted. I talked with a repair shop and they say there isn't any adjustment. He says the problem is the diaphramm in the carbs. Has anyone had this problem, and what was the solution?

Welcome to the seaadoo forum mobjack75. The carb settings on your seadoo are as follows; the Low Speed screw( has a pin through it) should be set at 1 1/4 turns and the High Speed screw ( has a plastic cap on it)should be set at "0".
It sounds like you need to remove the carburetors and clean them. If you're careful and don't tear or damage the diaphragms you won't need to buy a rebuild kit. Pay attention to the internal filters too. If you have gray fuel lines you need to replace them with black fuel lines available from auto parts stores like Auto Zone. Measure the length you need and bring a sample with you so you get the correct size. Replace one at a time so you don’t get them mixed up. If you need clamps replace them too. Use small stainless steel clamps also from the auto parts store. Do you have a seadoo shop manual? If not here’s an idea for you. You could join as a "premium member".

once you remove the giant black air box on top of carb and it's base plate you will have access to whole carb-side of the motor. go get a set of metric allen-head sockets. life is so much easier than trying to spin full length allen wrenches in the engine ciompartment. only about 15 bucks at autozone. comes 3 thru 8 or so mm. you will use 4, 5 and 6 a lot. while you are at the parts store, get some PB Blaster. best freeing oil in the world. soak the adjust screws before you touch them.
