We just bought this ski last weekend and we are already having trouble with it. The first problem is it is really hard to start. Then when it starts it will idle. If we give it any fuel at all it shuts off. I have checked the fuel filter and fuel lines and they seem to be clear. I have checked the compression in all three cylinders and that is fine. It also has spark in all three cylinders. Has anyone else had an experience with this. Any help is appreciated.
