A work stand for working on 4-bbl carburetors with the narrower bolt pattern (4.25" x 5.625").  This fits a Carter Thermoquad (shown in pic) and I believe also the Rochester Quadrajet.

This is based on the carburetor work stand print designed by archistrong, (https://www.thingiverse.com/thing:387375).

I printed this in PLA and it works fine, but for long-term, or heavy use ABS is probably better.

Updated 12/13/22: Replaced the original design with an updated version that has tapered pins for a looser fit.  

Updated 12/28/22: Added a new version with tapered pins that will fit the wider carburetors with the 4150 style base.  

Enjoy!
