Pulled the prop through on a Rallye tug on a cold morning, an aircraft renowned for being reluctant to start. A four blader, 180 hp, just come out of a cold hangar, oat -10.
Chocked, no prime, throttle closed, keys in my pocket. The ***** started, ran for long enough for me to walk round the back, get on the wing and reach down to the fuel tap.
Still have all my fingers, never wear a watch or rings when handling a prop or a battery. Beware clothing, too, especially scarves and long sleeves.
