to know how finally aligning the engine comes into play.

The installation procedure for the Rotax engine
has you verifying the cant of the engine to the
right by 1.5 deg. If not, it is adjusted with
AN960 washers. My manual says the top horizontal
tube should be parallel to the firewall also, but
mine was not (and Bob at Lakeland said not to
worry). Just make the two side tubes parallel
with the firewall. Mine came out very close to
1.5 deg. before shimming.
