venturi size

[sverny]

I think the venturi insert on my ec-125 Pilot Burner has fallen out during overhaul and now there is very little back pressure to the pilot which won't light. Does anyone know what the diameter is supposed to be for natural gas? I can make a new one if I know the right size of venturi hole. thanks all.

Attempting to mod a pilot orifice is not a good idea. Just replace the pilot assembly.
