Solo swinging - shurely an oxymoron!
But seriously folks -
Priming the engine then turning off the fuel is the safest way to avoid a long walk home.
Another thing many people forget is that the maximum draw during engine start is created with the hrottle closed.
In other words if in won't start, pulling the throttle back a tad often works whereas opening it progressively can lead to a sudden roaring sound.
Just taking things slowly and carefully is half the battle. As Bax once wrote in Flying Mag "Being called cautious is better than Lefty!"
