Thank y'all for your answers. I now understand that Picca on a Stihl bar means a 3/8 pitch but a Picca chain.
Questions:
1. Does that mean I can use a Stihl 3/8 2n1 sharpener on this Picca chain just like a "regular 3/8"?
2. Can I run a regular 3/8 chain in the right length on this Stihl bar, or does it have to be Picca?
3. I bought a .325 Stihl 2n1 sharpener. Can I buy a 3/8 file and guides instead of buying a whole other sharpening kit? Got any recommended links? I couldn't find any.
