i have a 1988 kawasaki JS 550. it will only start with starter fluid for at most 10 seconds then cut out. first thing i went to was battery. had power. and if it was started i have ignition. so i went to fuel. went through the lines clean and cleaned the fuel filter then cleaned the valve assembly solenoid. . .that is the only thing i can think of because the jet ski isnt getting fuel. lines are bone dry. what else could it be or is that the problem?
