John,

I've previously carefully checked the engine mount I have here, like yours
it's half a degree to the right so the same as yours. It's not easy to
measure the up or down as the four mounting points are not consistent
however it looks to me that our engine mount actually has a small amount of
nose up inclination. Guess also the up or down and for that matter the left
or right, depends on the firewall being installed on spec...

Reading Martin Hollman's books and in particular "Boggie with a Turbine" he
writes the engine should be pointed 0.5 degrees to the right and in the line
of flight ie 0' up/down.

ciao Roberto d'Italia.
