360
I have a 360, nice little saw. It's kind of the go-to saw for little stuff, limbing, cleaning up fallen branches after wind storms.
On my list of things to beware of, behind the little guard plate where the single bar-stud emerges, there's a small crack in the case. It looks like the PO overtightened the bar nut, or just torqued it super hard when cutting. I found it because I had trouble setting the chain tension, and the crack runs from the stud to the slot for the tensioner. The split caused part of the case to push out into the tensioner slot so I couldn't get past the crack. I used a dremel to reshape the slot back to where it should be, and now I can set the tension without issue.
I looked at the IPL really closely, and can see the stud inserts through the oil reservoir, and has a head like a bolt. I'm not super worried it's going to pull through the case, but I don't torque the bar very hard because of this, and I do check it every time I have the cover off for cleaning. This is probably not a normal problem, but something to check.
I think the PO must have been pushing it because the chain, with sharp cutters, wouldn't cut at all due to the rakers being too high. First time I've ever seen a sharp chain that wouldn't make even one chip fly.
