I've used Outerwears Pre-Filters on dirt bikes & atc's that I owned in the past and they were great in many ways, but they don't have the size I need.
This is my second saw that I purchased about month ago, last saw was an Echo CS 520 that I still have, but needs repairing. Anyway, I just want to do my absolute best in preventative maintenance on this chainsaw.
