I picked this up at Luray and I got it all cleaned up today and got all the brass out and cleaned up. Sadly the float came unsoldered but it was full of water so it would need work regardless.
I have found HT 3 1/2 on the brass plate along with 2 2 stamped kinda crooked on it. Like it was a after thought. I have keyed it into google and nothing came up. I know the throttle shaft is missing but I am thinking I can modify 1 from another carb to work. But I would want a float and needle and seat if they are available.But I aint finding these numbers or this style of Zenith carb online.
My 1924 Chevrolet truck has that carburetor. The down side of using it is the pot metal ventury inside that swells up and cracks the body. Mine is cracked but works okay except at idle, can never get it to idle really smooth.
