Single stage snow throwers are really picky, It's a learning curve when you start to use one.
A good rule of thumb after you make your first pass is to take smaller cuts, go slower than you think you should be going and relax.
Heavy wet snow is a PITA no matter what thrower/blower you use.
In deep snow, raise the thrower, cut the top half off, back up and take the lower half.
In dry fluffy 4 to 6" snow, go like a bat outta hell, take full cuts and have a blast doing it.
Slip plate or other graphite paint in the chute and auger flites are a must.
