Carb Rebuild Guide

Age doesn't really have much to do about it. I'd built almost 100 carbs by the time I was 21. The key is to have a nice, clean, roomy, area to use and lay everything out in an orderly fashion. Take photos periodically if you like. The FSM or the instruction sheet that comes with the kit should be sufficient to get the job done. If the carb was recently in good working condition, it's usually just dirt that screws them up. Take it apart enough to do a thorough cleaning and soft part replacement.(gaskets, seals, acc. pump, float valve, etc.). If you can leave hard part assemblies together, do so. No point in disassembling linkage unless it's needed to get the carb apart. If you just got a core and don't know it's history, you'll have a lot more inspecting to do....cracks, bent or missing parts, mismatched components, modified jets, etc. On a Holley (not my favorite brand) you can order a kit by the "list" number stamped usually in the air horn. If it's your standard 2 float bowl Holley 4bbl, pay particular attention to warped bowl covers and metering blocks. Some people get carried away cranking down those screws. Get some spray carb cleaner, take your time, and set all the adjustments the way your carb is supposed to be set and you'll be fine. Have fun!
