I have a Husky 340 chain saw with a 16" bar that I'm very happy with. I need a new file to sharpen the chain because I lost the old one, but I'll be darned if I can find what size I need to use, either in the manual or on line. The chain is original to the saw. The bar indicates it is a .325-66 32. What size file do I need - 5/32, 6/32 or 7/32? Thanks, Terry
