A couple of photos of the primary bowl and metering block cleaned up at component level then reassembled.
I didn't think to take photos of it when I first removed it but it was in far worse condition then the earlier photo I posted of the secondary bowl.
Apart from the gaskets the only thing I replaced was the power valve, it cleaned up okay and the spring seemed to be functioning properly but I don't have a tester to check it for vacuum so I couldn't get rid of this nagging doubt in the back of my head, what if it seizes up.
So in the end I decided to put in a new one.
I also removed the base plate and cleaned out the throttle body assembly (no photos) and used the air compressor to make sure there were no blockages.
I was using the tube style discharge nozzles with hollow screws (at front of the photos) and you can see how fouled they were.
I cleaned them up but ended up replacing them with the stock nozzles and solid screws seen at the rear in the photos.
Reassembled and ready for it initial setup before I fit it to the manifold and tune it.
I gave the body a minor rub down but didn't bother to metal polish it as most of it won't be seen.
You can still easily see the pitting the corrosion caused to the primary and secondary bowls.
