starting facing downhill

In my wildest dreams, I cannot imagine the incline has anything to do with your;" cranks but won't start" issue!

The Proof? Block the choke open, then just dribble a teaspoon off pure gas into the intake. Right away, push the gas-pedal down a bit and hold it there, then hit the key. It should fire right up. When it does, and stays running, you can lift off the gaspedal.
