Default YS-185 CDI Sensor problem


I fly F3A with a YS-185 CDI.

For the first 45-50 flights the motor worked perfectly. Then,it became irregular and it started "kicking".
Tried a different CDI unit, changed plugs and fuel with no effect.

On the test bench it worked perfectly "like a swiss watch".

When I moved the wire from the sensor in the backplate of the motor, the problems returned.
I concluded that there is some problem with the wire from the sensor.
I assume that I will have to replace the sensor.

Please advice what parts I have to replace. Can I replace the sensor or I have to replace the whole backplate assembly?
Could you help me with the YS part numbers?
