I just submitted the following question to stihlusa.com, and I figured some of y'all may want to see it and maybe take a stab. I will post their official response when I get it.
---
I have about seven Stihl saws, 441C, a 310 and an 021 among others.
My question is about my 310 and 021. My 310 has a 3/8 pitch clutch sprocket. My 021 has the OEM 16" bar with a Picco chain (.050).
Questions
1. What is the pitch of this Picco chain in actual numbers?
2. I recently bought a Stihl 2N1 sharpener, but I stupidly bought a .325" one because I didn't know what I was doing.
2a. Does that mean that the 2N1 files and guides I bought are no good on my 310 and 021 as described above?
2b. Do y'all sell interchangeable files and guides for the 2N1?
2c. What size files and guides do I need for my 310 described above?
2d. What size files and guides do I need for my 021 described above?
