ABSTRACT:
The invention relates to an indicator controlled by the ignition system of an i.c. engine, so that the indicator, e.g. an LED, makes an indication when the engine is adjusted to an appropriate idle r.p.m. or race r.p.m. As the carburetor is calibrated against such selected and adjusted r.p.m. the said adjustment will bring about a minimum of exhaust gases.
