Don't think the red light was limiting, just a method to indicate a certain RPM which reportedly decreases over time to the point you no longer use it.

Straight info from thread link. - Early models from early '91 to late '92 had the 'red light' LED and limiter coil with AL flywheel.

Loggers figured out the limiter and swapped in the non-limiter coil. Stihl figured out what was being done and came out with the non-limited coil model.
