The problem with the ROTEC TBI (Ellison) has been solved. It turned ou= t=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.
=A0
ROTEC statement:=94 Because the TBI has no float bowl, it will work in= any=20 orientation, even upside down=94=A0
I found out that if the slide throttle is horizontal in a side draft= =20 configuration, you can encounter the problems I had.
=A0
The problem showed up, with the slide throttle 5deg down at the =93ope= n=94 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.
=A0
I solved the problem with orienting the TBI 45deg up on the =93open=94= end,=20 after testing all variants I could imagine. This change included a unique d= ouble=20 acting Bowden cable throttle.
The last two straight TOL=A0 worked flawless.
