Pulled a Thermoquad (6139S for '72 340 auto) after a recent rebuild to check for vacuum leaks. Performed an almost complete disassembly. Put all loose parts in sandwich bags labeled A thru F (parts removed first went into bag A, then B, etc.) With everything bagged as I went, no chance of misplacing anything, right?
Today went to put it back together. After the main body screws were snug, found the metering rod covers with their screws in a bag but no metering rods. I have an old AVS carb on the shelf, but looks like metering rods don't interchange.
They were not dirty when I removed them, so no reason to believe they are soaking in a jar somewhere around here. And the funny thing is, in my own mind I had them in my hands once already today. Now I'm thinking maybe not.
I am going to check the refrigerator next. I have five and six year old grand kids here that get into everything, but I kept them away from this carb stuff and as far as I know they never had access to it.
