Wouldn't that entail a sensor on the motor itself instead of built into the coil?Theory of operation says. According to Stihl. They react to a lean condition introduced instantaneously and adjust fuel load accordingly. I know there is no such thing as instantaneously, but faster than you will notice in use.
Not addressing temperature , but reaction to producing a lean condition and interpreting the reaction of the RPM.
They will shut down if they reach a temperature threshold. But, I don't think that is involved in determining the fuel load.
I would think, and I have no idea on the actual function, that the temp sensor would help build the fueling curve.
