b31 18d1 box of tricks

[EDDIE SIMPSON]

i have a b31 with the 18d1 points unit. can anyone advise me on how to remove condensor and lubricate auto unit when i m in there. will i have to reset points gap if i take the plate off? no information on the internet.
i have a neg earth inductive discharge unit i am going to fit but unsure whether keeping the condensor is  necessary. but can the points run ok without the condensor fitted?
