The other thing is that the seats are screwed so far down that the locking nut has about 2 threads to attach to. Does that seem normal?

A genuine Holley style needle and seat does not use a locknut. It has a thin unthreaded nut that screws the seat in and out and then a wide sloted screw that locks it. If yours have thick brass locknut's then your guy put an el cheapo rebuild kit in your carb. That style nut is easy to overtighten and strip the threads in the fuel bowl. The cheap kits also come with cheap gaskets that shrink and/or stick and the powervalves are garbage. If yours has the big brass locknut's then you need to buy a good kit from Holley or Quickfuel and then find someone else to do your carb. I've attached a pic of the correct adjuster to compare with yours.
