I'll confess, the Solex 30 is black magic to me, prefer side-draught carburettors. Timing is most likely suspect for a complete lack of power, but I'd have a look at the colour of your plugs too if you haven't already, it's the best indicator of a fuelling issue.
As regards to the fuel lines, I would recommend replacing them if they haven't been done, if they're the original steel ones they will sooner or later fail. Although in your photos the one from the pump at least looks new.
I can agree that your distributor is pointing the wrong way, the vacuum advance unit should be nearer the alternator than it is. But actually that's because your leads are not fitted in the "usual" way, usually cylinder 1 is where your cylinder 3 is, basically they all need move one position counter clockwise (order is correct). I don't think this is your problem, it will still work like this. If you move them, it'll retard the timing a lot so it'll need advancing (rotate towards alternator).
How did you try to set the timing? Doing it by ear always works for me, but usually takes me 3 attempts, and tackling a decent hill to convince myself that it isn't going to ping/pink under load. Worth also checking the weights inside the distributor are free, and also that the rotating plate which holds the points is free to move too. If the centrifugal advance isn't working, you really will notice it.
Hope you get to the bottom of it, you have a really good looking car, I regularly think about adding stripe to mine ...
