/CAS's recently, I think there MAY be something you can do.

You say that you're fitting the CAS upside down?
Well, if you drill out the pinion dowel, pull the pinion off with a puller, and then rotate it 180 degrees and press it back on, the dizzy will function as stock, just upside down.

If you clean everything up, then you may be able to just rotate the pinion rather than removing it

(but it doesn't work like that, usually!)

IIRC, the pinion has an odd number of teeth, so you cannot simply put it on upside down, as you wont be able to time it up.

If you set the engine to TDC, and remove the CAS cover so you can see the trigger wheels, it shouldn't be too difficult to sus out how to set it to 10 degrees.

The top wheel only has one

"tooth" so you can line that up with the pickup coil.
