I have a 94 wave blaster, it runs for 2 minutes then revs out at 1/3 pull of the throttle, the motor also seems too hot for just running for 5 minutes. It idles fine and I just changed the spark plugs and CDI to a Pro-Tec. there's water going into the head when I plug the hose to it but I haven't checked it when it's in the water. Any help is appreciated, thank you
