Yup, output...I wanted to mix the air and fuel as much as possible.

Lynn:
Which way is the swirl pattern in the carb throat, clockwise or counter
clockwise?
And how did you determine it?

It is CCW...based on nothing in particular. When I built it, I was
trying to get fuel away from the #1 intake tube, because that
cylinder has always been a "cold" cylinder. As it turns out, I had
been chasing my tail trying to warm that cylinder up, and subsequent
readings have shown that you can't always get the same exact readings
from all the cylinders, so I quit chasing that dream. All my
cylinders exhibit the same color of plugs, the exact same color of
the exhaust pipes, so I stopped worrying about that one"rogue" cylinder.
My idea in making 5 blades in the swirler and mounting it with the 4
bolts was that if I wanted to try to change the relative positions of
the deflector blades to the intake tubes, I would get a positional
change if I took the swirler off and repositioned it one bolt at a
time, the incoming charge of air/fuel would be "aimed" a bit
differently each time. But it turns out that I never had to try to
change the position at all....it just worked pretty well, and I left
it at that. Truth is, I had forgotten that I had installed that in
June, and had been having no problems since I gave up on trying to
chase that elusive cylinder....which wasn't elusive after all, just
reporting different numbers for EGT than the rest. The CHT's have
been fine all along.
