<font color="#0000ff">Any other ideas?  I have a similar problem with my TT F54-s (airbleed carb version).  Except I can sort of reproduce the problem on the ground by flipping the plane up-side down with 3/4 -full throttle and manuvering the plane by hand as if it were doing a loop.  It looses rpm, smokes more, then dies.  The fuel line remains full of fuel.  These signs would indicate that it is running too rich when moving inverted.</font></p>
