Deposits, debris, and potential corrosion build-up can behave like glue. • Methanol: Since it has a higher octane level than standard gasoline, methanol delivers more complete combustion. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect If the tip of the spark plug is too hot it can cause pre-ignition leading to detonation/knocking and damage may occur.
