Well, after experimenting quite a bit and flying a couple of hours in different
configurations, here's my latest conclusion on my uneven fuel distribution:
I've ordered a Rotec TBI. :)
My flight with just the radiator hoes was awful.
After some more research, I tried modifying it with an .025 aluminum insert along
the 90 degree bend to stop any rotation and to help it around the corner.
That produced results better than the original SCAT tube but still very uneven.
Then I inserted another short piece of aluminum at 90 degrees to the first to hopefully
kill any rotation and get everything lined up before the carb.
Results: Even better, slightly, but still not acceptable.
I have essentially tried 4 different tube configurations to get the air from the
filter box to the carb, and while I have produced varied results, I have not
addressed the original problem to my satisfaction.
I spoke with the tech guy at Rotec, who said they had experienced similar problems
with the Bing, and while it was a great carb it was very sensitive to slight
imbalances and swirl in the flow. And he assured me their TBI was much less
sensitive to those issues.
I'll post under a new thread when I receive and install the Rotec unit. Fingers
are crossed.
