If so, weird…
Yes there is a piece bolted to the pull cord assembly.

Yamaha call's it a carb cover not a silencer.

I didn't take the time to look at the cover, but there isn't much room for that bolt to make it's way to the carb. I have seen were a screw off the carb will make it's way threw the carb covers.
