I agree, the color of the center of that spark plug indicates a 'lean' fuel /air mixture.
I may be assuming too much about your comment above but...
because of all the internal construction & operational differences, the jets in one brand and size of carburetor cannot be compared to the primary and secondary jet size in a different brand or model of carburetor.
They may be similar, but it is just as likely they are not.
A jet size that works well in one carburetor on an engine can be completely wrong in another brand or model carburetor on the same engine. The correct jetting in a particular carburetor is specific to the engine / carburetor combination and the altitude & other conditions in which the car is driven.

dmsfrr Thank you very much for your reply.
What he tells me is correct, I will try when I can make time to place bigger jets in the secondary ones and smaller ones to see which of the two configurations allows me to regulate the opening before. Greetings.
