Having problems one engine idle too high the other doesn't want to take fuel on start off with a little effort you can get both to run good at mid to top speed and both idle good except the on that idles around 2750 and the other around 2000 rpm in the water. any tips?

Welcome to the seadoo forum jmiles. 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.

The High Speed screw is set to "0". These have a plastic cap on them to keep them from being turned any more than 1/4 turn. The Low Speed screw is set to 1 1/2 turns. The screw has a pin through it. If you need to adjust the idle speed do NOT use the low speed screws to adjust it. Use the IDLE Screw to adjust both carbs at the same time. When adjusting the carbs be sure both carbs are in sync.
I hope this info helps you out.

Help!!!

Does anyone have a diagram or a picture i can't seem to get this right. The speedster i have only has one carb for 2 cylinders i know that has to change something. Thanks

The only thing it will change is you'll have to only adjust 1 carb.

No, probably the BN-40I carb on each. When/if you rebuild the carb, dont replace the float-arm spring, use the one in the carb...:cheers:
