For the idle miss/flutter, trial disconnecting the vacuum advance hose? (temporarily plug the hose off).
Also try removing the "exciter" (?) wire to the alternator. (mentioned in the Ti tuning instructions).
I do have another more complicated theory: The main pump diaphragm may have a minute leak.
PS I have never seen my plugs all look the same colour! (Only owned it 45 years though).
Keep us all informed.
