You have to look closely to spot this one; this metering block came from another carburetor that had been rebuilt multiple times but always ran very rich at idle. It took a while to find this, but upon close inspection,I spotted what I thought to be some porosity on the primary metering block. When the block was stripped, the issue became quite clear--there was a severe void covered by a thin "skin" of flashing that went from the float bowl side of the metering block directly into one of the idle well passages. No wonder it always idled rich! The metering block was replaced and the problem was solved!

Once everything has been reconditioned, everything gets stripped back down to bare metal in preparation for the re-coloring process. All of the zinc castings are re-colored back to their original appearance using the proper chemicals. You will NEVER find spray paint on one of my carburetors.

I can't show the actual re-coloring process for obvious reasons. However, below is a picture of all the major components stripped and ready to be re-colored.

Once all the components have been re-colored, the sub-assemblies go together with the appropriate new and/or reconditioned parts. No generic parts here!
