Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Welcome to JUST ANSWER small engines, let me try to help you !! Kawasaki twin engine. You have valves correct at .10MM, But I would run a cylinder balance test. Loosen the spark plug wires and with engine idling, remove one wire at a time. If engine dies when one is removed, the opposite cylinder is not firing, thus you have loss of power! If cylinder is not firing, then check for spark and compression.
