Lawn Boy Silver series metallic sounding noise when pull started. need help please.

Hi. Thanks to everyone on the board for having me. I have a lawn-boy silver series (model 10301) that has been neglected. A while back the pull handle fell off its holder and went under the mower. Thankfully enough of it was saved that i could pass the cord through it and knot it. It seems shortly after that time, I have notice a quick "cling" or a "ring" sound right before it fires up. I dont know if its related or maybe just something is loose. I dont know if I need to have it serviced or I can do it myself. Any help you could give me would be awesome.





Thanks for your time.
