First saw was a Homelite C-52, paid $35 for it used it for a few years til I got a MS290 and then I sold it. Wish I still had it, it was before I had CAD.
I clean mine from the bottom except that I shove a shop vac hose in there with it and just cover the inlet around the hose and brush shaft with a towel. works great and only takes 10 minutes or so.
