You can then richen it with a 3 mm Allen wrench in the hole between the plate and the fuel distributor.
You can reach into the opened airbox and access the arm from below it, as seen in Pat's photo.
This is not to take the place of testing but, until then, it may help get you up and running. To me, it sounds like you are running lean in your videos, but testing will help tell you if this is true and why.

Paul,
Souk’s procedure is good provided you don’t have unmetered air going into the system. I called his attention about it and he could not edit his posts because it had been old and no more access to old posts. Other than that, it is a remarkable technique.
So to set your mixture correctly you need to perform these basic tests first and foremost:
- Setting your control and system fuel pressures to specification.
- Verifying the absence of unmetered air going into the system.
