Hiya Grumpy, I had to remove it from the other mower to get the points and condenser out, but it came out so easily. in the manual its in the Ignition section 6 and also section 8 Powerhead teardown/reassembly 3rd page down. the photo attached shows a close up of the hair pin going through the flyweight and drive shaft. that little clip on the end is whats stopping it from going under and staying on the inside of the flyweight. your probably going to say take the clip off. But i didnt take the clip off to get the hairpin out it just slid out real easy.
