Can anyone help identify the screw thread and size for the small drain screw on the premonobloc float chamber?

I was planning on making an adaptor to a clear pipe so I can monitor the fuel level - part of the ongoing ‘it doesn’t run right’ saga

If you mean the blanking screw, it is either 2 B.A. or 1/4" B.S.F. according to "Know thy Beast."
