Precise carburetor adjustment is as easy as changing spark plugs with the Gunson Colortune kit. Different air-fuel mixtures burn different colors, and the Colortune plug insert allows you to see the combustion color while the engine is running; carb adjustment is then made to achieve the correct combustion color, and maximum power and fuel efficiency can be obtained. Very helpful in setting up twin carp applications! Kit comes with an ignition cable extension, plug cleaning brush and optical extension tube. Full instructions for operation are included.
