Carb Assortment
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 |

Re: Carb Assortment
lots of advice about carb cleaning on this forum... do a search for a plethora of opinions!
In the centraal pic the chip is well above the fuel level so you may be OK, but wise to thorughly clean eall and all blast them.. often cracks only become visible when they've been cleaned /grit blasted . Totally unreclaimable threads and cracks are usually the only thing that prevent rebuild if you use a rebuilt kit and ingenuity. "Is the upper shown in the lower left without the strainer from a side bowl unit?" Yes |

Re: Carb Assortment
Soak in Evaporust or rust 911 before taking apart, it will help loosen screws!!

Re: Carb Assortment
I don't know if you have any experience with A carb/Zeniths. Should caution you about taking them apart. First, Don't try to twist them (A s and B s). Some fall apart, some are so stuck that they will not come apart for anything and must be soaked in Kerosene or some other solvent. Forcing them apart can break the pot metal venturis. Also, be very careful with the ears on model "B" carbs Good Luck!
