Can anyone advise on the specified readings for testing my CB77 ignition coils. On mine
The primary circuit readings are 3.5 and 3.8 ohms
and secondary circuit readings are 8500 and 8600 ohms
I have it in my head that the primary readings should be around 1.4 to 1.8

Without looking them up I'd say they sound OK.
Typically coil ignition primary values are between 2.5 and 5 Ohms
ET (Energy transfer) or 'magneto' system primaries are usually are 1 ohm or less
