Koso Exhaust Gas Thermometer "EGT" blue lighting

Very useful instrument by Koso for adjusting your engine and carburetor.

It measures exhaust gas temperature (EGT). It is measured in real time. As a general guideline - lower temperatures are indicative of rich air-fuel mixtures, (very) high temperatures of lean mixtures.

Easy install, no welding required. Manual and instructions are in English, as always with Koso products.
