I just bought a Husqvarna ST224 snow thrower and there is a problem with the right hand (auger) lever staying locked down when the left lever is held down. The hook on the right lever will not completely lock the pin on the handle and it just pops back up. I don't see an adjustment for the small cable that goes from the left handle to the right handle. Can someone please help me resolve this issue? I called customer service and they were no help at all!
