I picked up a pretty nice 10323 off Craigslist for 25.00. About the only thing wrong with it was a cracked primer bulb and a governor spring that was bent out of shape. A Tecumseh primer bulb off a 3hp 2 cycle snow-blower will fit a Duraforce housing, looks pretty much stock (and its rubber not plastic). I never cared for the plastic primer bulb that came on the factory Duraforce, seemed kind of chintzy to me. Sorry no pics, never could get my old Mac to download a picture, and now my cell phone picture say they are too large to upload.
