Can you run a 3/8 chain on a 346 ? I like only having 1 chain size for all the saws.
If you're talking about running full size 3/8" chain on the 346XP it will take away from the saw a bit IMO. The super high revs of the 346XP + more cutters per loop in .325 chain is what makes it such a light-sabre to begin with. Going 3/8 (not low-pro/picco) will introduce a much larger cutter profile, slowing the saw, and there will be slightly fewer cutters per loop. Assuming your rakers are set to the same depth, 70 cutters cutting .030" (just an example) each will cut deeper each revolution than 60 cutters taking the same .030" each. Difference will be a wider kerf, taking more wood which lowers RPM's, compounding the slow-down.
Why 1 chain pitch across multiple saws? It only reduces the number of file sizes you need to have on hand. Your chains won't be interchangeable anyways unless your bar lengths are the same and even then it can be 1, 2, or even 4+ links difference across brands/mounts. I can handle bringing 2 or 3 files in the woods as opposed to 1 but babying a saw all day that has too much chain on it is just aggravating and counter-productive.
