RE: CH ignition versus Chinese version.
Ralph, I just mounted my sensor on my 3W100 and when standing in front of the motor the sensor is now hanging to my right. In other words I remounted the sensor to the right. Looking from behind the motor the sensor is mounted to the left of center.
Since this whole thread has been confusing and no instructions were provided with the RCEXL I'm taking it that I SET my total advance and the unit retards only.
Is this correct?
