ECHO CS501bar mount

[junkfxr]

I keep finding conflicting information and am hoping someone here has had the experience to give me a real answer. I'm contemplating buying an Echo CS 501 but they only come with .325 chain. I run 3/8 x .050 on all of my saws for a number of reasons, even on the 50 cc saws, but I can't find what bar mount that the 501 uses. I have found 3 different listings for it. I have a CS 620 that I made 12mm x 8mm bushings for the bar studs to be able to use a D025 (Stihl) bar so that it will use the same bar and chains as the rest of my saws. Works fine without having to grind or drill on the oil holes. I'm hoping that the 501 will be as simple. TIA for any insight.

Filing tensioner holes on a k095 mount bar works great.

It’s a goofy bar mount that not many other saws use, so you might be looking at only Echo or possibly Oregon replacement bars. I’d put a k095 small mount bar on it and file the tensioner hole slightly. Works like a champ
