Part 10 looks to be a roller bearing...I hope this isn't part 10
Hopefully you find more than one...maybe two or three moreThat's what I found next to the cylinder
The old Windsor bars a actually a milled bar , there's quite a bit of difference in weight.After a little over a year of looking all over, finally have a good supply of new old stock homelite bars for my CS 900 EVL. No thanks to those goofy light-weight bars on an old muscle saw. Love those old solid bars!
