I have the 13 BREW. What did you do to change back to the old style CAS?=
 Wouldn't I have to change the front cover and e-shaft?

Do you know anyone that would let you borrow their EC-2 to try?  You want=
 one configured for the old style CAS.  This is what I did and it confirme=
d that the CAS was causing my problems (same as yours).  I finally gave up=
 on the crank-mounted CAS and went back to the original style CAS.  No mor=
e high rpm mis-fires. =20
