BME50 Choke Lever
Except for the 20 years ago, The pilot could have been Jerry Kitchen, with a Meister Corsair..He was at the QSAA in Vegas around 1989, doing touch and goes about 3 mph into a slight headwind...Like you said, the crowd loved it....
The Ether in spray cans works good, too, but a little goes a long way !!!!!
