Is the tape central height wise on the ACE head (audio/control head) and is the arm that pulls the tape to out from the cassette going to full position? Also is the ACE head vertical both sidewise and forward/backwards? Too much tilt on the ACE head could well cause issues.

It might be worth checking continuity on the screened leads between the ACE head and the pcb where they connect to. Also check for dry joints on their soldered receptacles.

An oscilloscope would be useful here to check that you are getting control track pulses from the ACE head.
