Pull start won’t engage / noise when running TRX350 2001

Hi everyone. I’m new to this forum. Just bought a cheap 2001 Fourtrax trx 350 that drank a little water. Oil was still a little grey after 2 oil changes. After that it was smoking like a train…

Piston and cylinder were in good shape. I change the piston rings, valve springs, seals, etc. After that it was running very good, besides a little winning sound after shutdown…

But yesterday an engine ticking sound started slowly. It is now pretty easy to hear it. Never heard a bad one way bearing, but it sounded like the valves. So I went to readjust the valves, but the the pull start is now turning without engaging (it was before). The electric starter still works fine.

Could the ticking sound and the pull start not working problems be related??

Thanks
