I have a Stihl 361 that I keep a 20" bar on most of the time and it runs great with it. I use full comp chain though, no reason to run skip on a 20" bar really. I also have a 24" bar for it, full comp also. It will pull that just fine, not super fast, but will do the trick. Maybe a skip chain would be better on the 24", especially in hardwood, but I think 20" is better on this size saw. What are you cutting with it?
