So i purchased two jet skis to try and enjoy the summer with, i took them out today for the first time. my 97 seadoo bombardier is a little difficult to start, it cranks a while then fires up but it wants to stall unless i keep on the throttle for a minute, once its running it idles fine. now when i go to accelerate it will die out 50% of the time, the other 50% it runs and flies perfect. are these two problems related and is it just dirty air cleaners or bad plugs, i am a very knowledgable mechanic for cars but this is my first experiance with jet skis and any help would be greatly appreciated. but for the most part it ran fine today just sluggish at certain times.
