Tecumseh 5148 carburettor idle screw, a picture or number needed

Hi,

Things that seem to happen... I just found out that the idle screw from the Tecumseh carburettor on my Atco Balmoral went into... I guess the lawn.
I knew something was up, the revs where not stable, a bit of hunting. That's not normal.
I wanted to adjust the idle, picked up a small screwdriver, and somehow it would not fit up a screw, after getting a LED torch it was obvious. It was gone.
Now I need a replacement idle screw but I do not how the screw looks for this particular carb.
The carb is a Tecumseh 5148, it sits on a AQ 148 engine.
Does someone have this engine with carburettor and is willing to make a picture of the idle screw and post it here?
Maybe someone has a partnumber?

Thanks for your help, I really appreciate it.
Regards, Henno.
