Having A Tune-Up Performed
A complete engine tune-up, including replacement of the PVC valve, spark plugs, distributor cap, rotor and ignition wires (if needed) should be performed annually. Also, some engines require adjustments for spark, dwell and idle. All of these functions require special knowledge, tools and test equipment.
For this reason, MasterCraft strongly recommends having the engine tune-up performed by your Dealer.
