Weedless handle assembly Challenger 1800

[Chief120865]

I was out yesterday. Seemed like weeds were clogging so stopped, pulled handle couple of times and then whole handle came loose. It appears the pin fell off, but hard to tell if anything else as putting pin back in doesn't allow smooth operation. Looked at part explosions but hard to tell from those pix what is correct. Anyone have a picture to share so I can compare?
