"Now for something completely different". (Monty Python).
I always approach the flight line with only a push-on NiCd glo starter, a 4-way wrench, a small shot of priming fuel and a spare glo plug. The prop wrench goes in my right pocket, along with the prime syringe. The NiCd goes in my left pocket, making sure nothing else in in there to short out the battery.
My pit crew has nothing to clean up after me, and I don't lose anything.
