Also, are you sure the choke is opening up all the way ? I see the ground wire for the heated thermostat cap is not connected.

Precisely what I was telling you is that as soon as I give more opening to the secondaries, with the regulation screw, the bog is produced immediately. I checked it out with the bread twist ..
In the image you can see what you can open without bog.
As for the choke ... it opens completely and the ground is connected to the carburetor as it comes by default.
The change between the two jets was important, the engine became more responsive .. it was kind of slow with the 56.
