Which carb did you get ? You shouldn't have to do much other than idle adjustments.
Static timing the engine will probably be fine with the correct points gap of course.
If you get some really crappy petrol in Africa or elsewhere and the engine starts to "pink" [or "ping"] a very simple cure is to slacken off the distributor and retard the timing by rotating it a little bit .You then tune the engine "by ear" .
You will be able to hear the difference in the running of the engine as you rotate the distributor .Turn it until the pinging under load cannot be heard.
But before you start you should mark the original position of of the distributor so that you can return it to that position when better fuel is available .
Old Landies are simple reliable machines if you look after them and will run in unbelievable conditions and on the crappiest quality fuel so I shouldn't worry too much if I were you .
Get a manual or see if you can download bits of it .
