Check the following: * Inspect, clean, and/or replace the spark plugs if the spark is weak. * Ensure the spark plug gap and heat range are correct; adjust or replace as needed. * Replace old or non-recommended fuel with fresh, recommended fuel. * Check all ignition connections and tighten if loose. For incorrectly installed spark plug wires, incorrect ignition timing, or mechanical failure, please see your dealer. If water is present in the fuel, replace it with fresh, recommended fuel.
