Hello All
Very New to the Jet ski World, But ready to learn more about them! I currently bought a 1998 STX Kawasaki 900, carbs rebuild, I should say cleaned, fuel filter changed, and spark plugs changed, there's always been some hesitation not sure why that is my question, ran about 20 gallons of fuel through it but low grade, is that what I should be running or should I be running premium gas? For some reason now it acts like it wants to run off of three cylinders but only hits (2) I can't get it past 20MPH, and I'm not sure of the reason after I had a great three day weekend last weekend on it? Any help would be much appreciated
