Got the 920404 HD special ( smaller engine, plastic chute and manual cap ). When the auger didn't disengauge, I did the adjustment as per the manual and I couldn't make it work. idler/ engaugement arm seemed jammed and the belt guides did not look right. Took it back and got a 920404 snow tek 24E, the real model. with larger engine, steel chute and automatic chute cap. In the box, and put it togther, knowing an HD employee was not involved.. Still firing this 1 up, the auger remains spinning no matter what. I have not yet adjusted anything. The manual sucks.. anyone familliar with Ariens snowblowers? This is the same machine as the Ariens compact 24, without the light and an LCT engine instead of a B&S
