So Richard,
 
Why causes the problem with the origination orientation of the = TB  =E2=80=93=20 does the jet leak, fail to fee fuel in that orientation =E2=80=93 = airflow problem?

Another update, hopefully the last one on the engine.
 
The problem with the ROTEC TBI (Ellison) has been solved. It turned = out=20 that a statement by the manufacturer is not fully correct, if not=20 misleading.
My problem was engine cut out at WOT. This only occurred at high = speed=20 taxi, not on the test stand.
 
ROTEC statement:=E2=80=9D Because the TBI has no float bowl, it = will work in any=20 orientation, even upside down=E2=80=9D 
I found out that if the slide throttle is horizontal in a side = draft=20 configuration, you can encounter the problems I had.
 
The problem showed up, with the slide throttle 5deg down at the = =E2=80=9Copen=E2=80=9D end.=20 This is the difference between the horizontal orientation on my test = stand and=20 the installation in the tail dragger on the ground.
 
I solved the problem with orienting the TBI 45deg up on the = =E2=80=9Copen=E2=80=9D end,=20 after testing all variants I could imagine. This change included a = unique double=20 acting Bowden cable throttle.
The last two straight TOL  worked flawless.
