We used the same length of tube used to balance the air flow through the
carbs and listened for a flow of air around the joint. Perhaps a little
slower but safer than either of the other methods mentioned. One of the
chaps in the tuning bay had a stethoscope with a metal tip in the end
instead of the medical type tympanum. (Didn't know if that was the right
spelling so I looked up
http://www.wisegeek.com/what-is-a-mechanics-stethoscope.htm on this 'ere
internet-webby thing)
