Glad you have started to move forward sorting it. I have seen oil coolers blocked up a lot worse and still not causing too much of a concern, but it is definitely a good start. I would check the timing now you have a new cap, that old one seems to have been a factor.
Don’t get too fixated on the temp on the gauge, use it more a guide to what is normal and what isn’t, but regardless 130 after 20km is a red flag, especially if you are going hard. Other things that can contribute are poor mixture(lean), advanced or retarded timing, poor fuel quality( tends to cause other issues including rough running) worn or wrong carbs, worn or wrong distributor, etc.
They are relatively simple engines but 50 years of people fiddling and mechanics who think they know better than the engineers who designed them contribute, and variable quality aftermarket replacement parts can all contribute to things not being quite right.
A good example is there are a ridiculous amount of variants of the original solex twin carbs that all look basically the same, but they have to be a matched set to each other and also to the engine, distributor and even gearbox. Auto and manual, plus different levels of emission control equipment, 1700, 1800 and 2l and year and market sold in. One side stuffs up and someone has a similar in an old engine so wack it on and it will work closely enough but never quite right, then add a few other adjustments and aftermarket parts and things continue going down hill.
Anyway, looks like you are on the right track, get out an enjoy it.
