Hi Graham,
Thanks for the note:
Ira
It puzzles me too. It's certainly constant vacuum, the spring restrains
the
diaphragm until enough force is created by the vacuum to compress it. The
force is pressure X area so it's proportional to pressure, area being
constant.
Fuel is pushed through by the ambient pressure on the carb float chamber,
so that will decrease with altitude , Seems to me it will be partly
compensating for the altitude but not completely. Still scratching my
head!
Graham
My question here is: is this not the same mechanism for slight reduction
of fuel flow with altitude for any standard carb, i.e., less venturi drop,
less vaporization?
