Carb Assortment

[rickranger]

Recently got my hands on a box of carburetors of various type and condition. May have been a junk pile.. There is one Model A unit and Model B unit in decent shape that I will likely rebuild for myself (upper left and upper right). Though the Model A Zenith has a chip in the upper half flange. Not sure if that chip is a showstopper as long as it seals, but I should be able to replace it with the orphaned upper half that is shown below it. Is the upper shown in the lower left without the strainer from a side bowl unit? There were also two Tillotson's in there that I have not taken the time to identify.

http://jmodela.coffeecup.com/carbs.html This site seems to have Model A Zenith's pretty well documented.

At which point is an upper/lower casting no longer able to be restored. What is the best way to remove internal rust where you do not want to bead blast.

Also if you are interested in any of these please PM me.

Thanks
