Hi MadNatDid you fix it yet? Intrigued to find out what the problem was.
Yes, indeed probably you missed my earlier post - no problem:
When you know it, everything is simple...
Thanks to your tips, I made new holes in the plastic mounting of the coil board and mounted it as far away from the Right Trough as possible - and lo and behold, everything works fine again!
Thank you all for your help in solving this problem!
