Believe me...I'm just as confused. When I spun on the actual 372 clutch. ...the leak went away

My guess, it wasn't holding the crank sleeve tight enough against that tiny little oring or letting it rub the seal lip they wrong way.

Can a 372 be pressure/vac tested without the clutch on?

Yes and no....the clutch holds that bushing tight. ...so...you can try testing it....but it won't be an accurate test...
Fyi....the 440 has basically the same setup

Maybe with saws liks the 372 & 660 being copied & sold with complete parts availability, Hoosky & Stihl made slight thread changes on the 570-576 & 661 clutches so AM parts would not fit & work. Its the only logical reason for such parts madness!

Ok so the truth is not properly. So the wrong clutch being not seated properly could very well have been the cause of the air leak. Hopefully it’s all good now!

Actually no it does not take me that long to cut a pop-up piston but I don't have the lathe at my house I have to go down to my folks place based on the fact that I still have a hundred and eighty-five pounds of compression maybe not all is lost but who knows
