Yes there is. Look closely. That's the set screw and adjusting nut for the front float bowl that's been epoxied over. Look CLOSE. You can see the hex of the nut.
To the OP that carburetor is someone's factory Holley for a spread bore manifold. It's not an aftermarket replacement. It either came on a GM or Chrysler product, most likely Chrysler, since it has Chrysler throttle linkage. Find another carburetor. That one has very lean circuits. That coupled with the epoxy on the float adjuster and I say throw it in the trash.
