For those who noticed. This saw does not have the original muffler. when i got the saw it had no muffler, i installed one from another 10-10 that is in pieces. with the different muffler I had to install a different cylinder shroud which doesn't have the notch for the plug wire to go behind the battery pack.
I don't care too much about that though, if i happen to run across the correct parts I may install them one day
