I have a homelite super xl with what i thought was a 16" bar. I went to the local tractor supply to buy a new chain. I found an Oregon replacement sor the saw. 60 drive links, 3/8 pitch,.050" gauge. brought it home and tried to put it on. Too long!! I counted the drive links on the original chain and there were 59. I thought the bar was 16". I believe it is the original. Now I can't find any bars. It needs a new bar. anyone have any ideas?
