Something tossing around in my saw!

I've just bought an almost new husqvarna 372xp pre xtorq and i just replaced the fuel line and tank vent. After putting it all back together, and before starting it, i audibly noticed something smallish rolling around what sounds like the muffler, bar oil reservor, or inside the recoil starter, which the starter i did pull and nothing rolled out. My husqvarna 365 special very faintly, very muffled, sometimes makes the same sound, but only occasionally. What the heck could this be, and it normal? Bar reservor is empty and I've not pulled the muffler yet

Video of the saw running and making the sound might help.
Could be a broken part of the muffler internally, could be the filter off the oil pick up line, or fuel filter off the fuel pick up line bouncing inside the tank. Could be clutch noise from a bad needle bearing, or worn clutch components. Could be something inside the starter cover being bounced around by the flywheel.
Worst case scenario is part of the engine internals has let go and has made it to the muffler- like part of a main bearing.

my bad, it was just the bar oil pick up line flopping side to side in the empty reservoir. Much relieved even if i feel like a big dummy. Took the saw out into the sunlight and looked inside the bar oil filler hole and synched the sound with a visual on the line, which has metal screen on the end

Leaking fuel issue resolved and saw back together. Back to making lumber for my wifes sauna ceiling again!

One of those things- you dont know if you dont know....... until you do know!
None of us knew the answer to every saw question from the get go- you learn through experience- and we are all still learning.

My lovely wife said to start it and see if it affected anything! I told her that the saw was parked until i figured it out. No way was i going to subject high rates of spinning parts to some mystery piece of metal floating around in there! I was horrified thinking I'd ripped about 5 feet of a 30 inch in diameter red fir when I'd ran out of gasoline on account of the tank vent! First run of the 372 XP and it definately has noticable more power than my 365 special

Yeah, if you have an unknown suspicious noise and it sounds metallic- probably not a great idea to spin the engine 12-14 thousand RPM and see if it gets better or worse, until you figure out what and where it is.
In this case, it was simple- but if it was part of the engine letting go internally, or a bolt bounding around the flywheel........

Personally I am not a great fan of the 365- a lot of people love them and to them, they are their only "big" saw. Me I cant see the point when you can get better from the same size with the 372. Okay initial cost might be a wee bit more- but worth it for the power gain and no weight/size gain.
Usually I go for the biggest in family size saws- but I will admit, for some reason I prefer the 85cc over the 90cc in that shape. Maybe the 90 is too close to the 95?
