Technical data:

  • candle type: cold

Definition of candle heat:

If the engine runs properly on spark plug A, and after replacing it with spark plug B, the needle is required to achieve full - even rpm (depletion of the mixture) it means that spark plug A is warmer than spark plug B. Candle B requires the supply of additional heat from the combustion of a more depleted mixture to achieve optimum operating temperature.

Correct selection of candle warmth allows for an increase in RPM by up to 2,000 RPM, correct adjustment of the mixture composition to guarantee high power and engine durability, and allows to improve the so-called "transition" when changing revs. A candle that is too cold causes a decrease in power and a bad "transition". Too hot a candle causes premature ignition, engine heating and detonation combustion, which can contribute to damage to the candle.

CAUTION !!! The supply voltage of the candle should not be higher than 1.4V. Otherwise, there will be destruction (burning) of the candle. If the candle is supplied from a battery with a higher voltage (e.g. 2V), use an additional resistor or resistance wires to reduce the voltage.
