My personal rain dance apparently looks a lot like working on the plane. It's
done nothing but rain since the Rotec was installed.
This type of thing has happened so many times that when farmers have their crops
dry out they call me and ask me to work on the plane and get it ready to fly.
As soon as there's a break I'll post the outcome.

I sent some pictures to a request for details, so I decided to make some notes
and put them here as well. So, here goes.
This picture just shows the Rotec TBI and the regulator, attached in a way that
I decided would fit within the confines of the motor mount on the lightning.
The 90 degree elbow is an AN-6 to AN-6 fitting. Then an AN-6 to 1/4" NPT goes
into the regulator. The fuel input side of the regulator is fed with a 1/4"
NPT to barbed fitting. I found the AN-6 to AN-6 elbow and AN-6 to 1/4" NPT online.
The 1/4" NPT to barbed fitting was acquired at NAPA. I saw an installation
that did something similar and relied upon the 90 degree elbow to support
the weight of the regulator. I did not like that idea since vibration would
work harden and most likely crack the aluminum elbow. Not good with fuel under
pressure, so in later pictures you'll see the bracket that prevents this vibration.

This is a shot of the adapter plate I made. It is 1/4" phenolic with a 2.25" aluminum
tube epoxy/flocked into place. The holes are match drilled to the holes
on the flange on the TBI. With this plate in place, the TBI is a drop-in replacement
for the BING. The other side of the TBI already matches the Bing,
and will slide into the rubber intake coupling on the Jabiru. With this adapter
I can attach the SCAT tubing that previously attached to the bing. The length
front to back ends up identical. The tube I used is slightly larger diameter
than the bing, but the SCAT tubing still fits just fine.

Two different angles that show the adapter plate on the TBI with the whole assembly
in place on the engine. You can also clearly see the aluminum bracket that
reinforces the regulator from fibration and bolts on top of the phenolic plate
and connects two bolt holes on the regulator. You can also see the regulator
override control. The cable end is affixed to another bracket that picks
up two of the regulator holes. The cable attaches to a piece of 1/8" aluminum
which pivets off of two aluminum angles and a 1/16" piano wire. When that cable
is pulled it pivots back and presses the regulator override. You can also
see another 1/8" aluminum angle at the bottom of the block of phenolic. This
angle provides an attachment point to bolt a cable clamp that holds the mixture
control cable. In the first image you can just barely see the mixture control
cable curving from the bottom right corner of the picture and peeking just
below the motor mount before it is clamped in place.

Sorry this is so blurry, but it shows the previously mentioned mixture control
cable and mixture control in idle cutoff. Also you can see the throttle cable
that curves straight up into the throttle control slide on the bottom of the
TBI.
