Buck, I wrote the article about straightening the Rochester castings using a gas BBQ grill. It was supposed to become a tech tip, however I am not sure it ever did. I'll search and see if I can find it. If the carburetor was rebuilt and the power circuit wasn't addressed it was definitely not rebuilt professionally.
Sadly you cannot buy a new Carter YF carburetor unless you get really lucky and find one on eBay or Etsy that was never used and has been sitting in somebody's shop for a long time. Fortunately Carter YF carburetors respond well to a good rebuilding. I can't really say much positive about Rochester B type carburetors.
You can use an electric fuel pump but only if you get the right one. Since 1997 I've used an AutoBest F4027. It produces 3 to 3.5 psi and works very well. Cost is about $30 on Amazon.
