Keebs if you have the lnb-f cocked a bit, then 1 of the legs that are bolted to the scaler ring may be bent at 1 end or the other need to use a ruler an do alot of measuring to get it in the center of the dish. you can even use a lazer pointer taped inside the feed throat to help you get it centered. now was looking tru some of my satellite paper work the other day an found a Perfect 10 spec sheet, an will give you the info for a 7.5-foot perfect 10 dish, that may help you out.
F/D ratio> .375
Gain@4GHZ> 38.7
Gain@12GHZ> 47.2
Percent Efficient> 60 percent
Focal Lenght> 33.75"
These where all taken from a Perfect Spec Sheet, an I didn't know that they made a 14.5-footer also.

Now I know that the BSC-621 does not have any of the F/D ratio stamped on the side of them like a Chapperal has, but what i do here is take a old feed that has the markings on it, an lay the 621 right next to it an mark it with a sharpie pen, then my F/D is right on.

Now have a G-box here running a 10-footer with a Pansat-9000, but don't know if the working of a Fotec is close to that of a Pansat or not, never owen a Fortec. but if it is let me know an will help you out with the motor control end.

Hope all Helps Keebs, need to get her up an running.
Captain
