Smokey fiddled around with it but never got it to work very well or
reliably. In an old Circle Track article he acknowledges Jack Evans as
the guy to talk to cuz he made it work! Success or failure has to do
with the way you handle the vapors produced and where to vent them. If
you don't get it just right, along with the proper flow rate, etc. it
won't work. That's why Jack got the patent on the system. It works,
under all kinds of stressful situations.
