Hello. Does anyone know what parts of a gas inspirator (venturi)
primarily affect the fuel/air ratio? I've tried searching high and low
for the answer to this and can't find it anywhere. It seems like a
black art or something.
See, what I'm doing is building a reproduction of a pest scaring device
which makes a loud noise to scare away birds and animals from crops,
just in case anyone was curious. The goal is to have an adjustable
fuel/air ratio to vary the flame speed. This changes the "tone" that
is produced. Maximum flame speed occurs when the mixture is
stoichiometric and tapers off on either side. Maybe someone has
made their own custom burner?
Thank you,
Robert
