Modified carb cover
The hole drilled next to the float valve is the new second atmospheric pressure vent.
Here are the two new ports. I would later cut them shorter.
Fuel pickup ports
the fuel pickup ports are at the back of the float bowl (top of the photo)
Fuel pickup orts
This is the orientation of the carb on the engine. Front of the car is toward the bottom of the photo.
This shows the orientation of the float and how much of the float bowl volume is taken up by that float.
Filter mesh material taken from a fuel filter and cut so that it fits inside the brass housing I made.
