The next time you open one of those Carburetor overhaul kits, take a moment and study your parts carefully, both those you got, and those you're replacing. Once in a while, not often, manufacturing flaws, packaging mistakes, and generally quality control of all sorts fails, the result can be frustrating, time consuming and costly.

In this first example, the accelerator circuit jet is the culprit. Under normal circumstances, depressing the accelerator plunger will force fuel through the spring-loaded valve in the top of the assembly, then through the orifice on the side, then the galleries in the float bowl, past the two jets above the choke, and finally into the venturi. Notice in the photo below the side orifice on the left specimen. The right side specimen, fresh out of the package, has not this hole. In effect, this manufacturing defect has, if installed, effectively disarmed your accelerator circuit. In cases of a carburetor rebuild with no beneficial acceleration effect, this just may be part of your problem.

This next example is downright amusing. Sealed bag, part number 411 810 00 69 plainly visible, this should have been the little chrome hood ornament for the UNIMOG. Factory quality assurance obviously was out to lunch as this one went down the line.It reached us in the same condition,flawless!
