Feb 24th – Soaked the metering blocks again and scrubbed the snot out of them. Reassembled the carburetor and started doing the off-car adjustments.
Did some reading about the Idle Mixture screws and the Power Valve. Not sure what size power valve my kit came with. It is stamped “1 G 8”. Valve for my carb should be a 6.5, and should be stamped with a 6 and a 5. Also, my idle fuel mixture screws are a bit grooved, and one is blunted! Need to get a new set, and pick up the correct power valve as well, just to be safe.
Feb 26th – got an email back from Walker, the carb kit manufacturer. They said that the power valve in my rebuild kit is rated 8.5” Hg. Since it should be a 6.5” Hg unit, I’ll have to buy a replacement.
Shopping List;
- Power Valve (6.5” Hg)
- Idle Mixture Screws
- Carb Spacer-to-Intake Gasket
After thinking about it a bit, I need to pull off the Primary Metering Block and make sure that the tip from the blunted Idle Mixture Screw is not loose / stuck in the metering block anywhere.
Also researched my carb-to-spacer-to-intake gasket options. Stock / factory for both carb mount gaskets are four-hole style with a tab for the pcv port on the spacer. Mansfield Mustangs has them. My spacer is non-factory, so it doesn’t have the four-hole style, it is a “two kidney-beans” kinda shape. Which means there would be unsupported gasket hanging out in there, which could result in gasket bits eventually falling off into the intake. I also found a Fel-Pro gasket that has the proper tab, and 2 pinches in the middle (PN: 60068-1).
Posted on the forums to get some input and see if it really matters what I use.

Went into the garage tonight after the family went to bed. Pulled apart the carb primary side, removed the power valve and idle mix screws and checked all the associated ports for the needle tip. All the ports are clear, so it was probably lost / broken off at some other time.
I also adjusted the secondary throttle stop position, setting it to “just touch” plus a smidge over ½ turn. Removed the dashpot and backed off the main idle screw, then set the main idle to “just touch” plus 1 ½ turns, per the Ford manual.
I also started to remove the driver’s side mirror. Found the rear-most riv-nut was packed with Bondo, and the front nut spun when loosening. Got one screw out and was able to get the front one loose enough to swivel the mirror base a bit. Looks like a good coat of filler under there! At the very least I need 2 riv-nuts on this side. Put it all back together for now…
Driver’s mirror base and gasket (who paints gaskets??)

Front lip of the door below the mirror, you can see some form of repair work…

Ah, the magic of body filler! What can it NOT do??
