Pitch question

[Bradencarving]

I want to run a 16 inch bar and chain on my ms 271. The sprocket on it is..325 x7. It came with a 20 inch bar.
What bar and chain specs do I need to get the rightsetup?

If you want to keep running the .325 you will just need to buy a .325 bar and a new chain loop. If you want to change pitch you will need a new sprocket and bar to match the chain you are wanting to support.
