This sounds like one of the small screws that hold the aluminum cooling fan 
shroud on came loose and is bouncing around in the depression off the back side 
of the fan. :O
 The cure for this is to pull the cooling boot, generator, outer fan housing, 
and fan off the engine, so you can get access to the screw that "fell" out. 
Russ says the stock muffler can stay put, and I've even tried it myself to 
verify that it's possible. You'll probably need to replace the screw, and you 
might want to check the other 3 while you're there, and even remove them and 
loctite them back in place. I normally add some silicone to the pockets (as added 
insurance) after the screws have been loctited and torqued to spec. Jim A. even 
suggests tapping them a little deeper and using a longer screw with loctite. 
I hope this helps.
