Thank you Paul,Duncan,Graham&Ira for your comments on e.g.t's as i have 100
C differences front to rear and was rather concerned with this, the fronts
running around 700 C and the rears around 800 C with side to side ,left and
right within 10-15 degrees so do we put this down to bad distribution of the
mixture.What effects does this have on the efficiency of the engine?More
importantly the poor old pistons ect. Phil George.
