Has anybody swapped out the factory carb with a Holley or know of a reliable replacement for a 74 opel manta 1.9? Also, will an electric fuel pump be needed?

The original carb on my 73 Opel GT project is shot. Somehow the primary is completely fused shut. I've given up and begun looking for a replacement. I found the Weber 32/36 but I'm looking for other options. At this point I'm just trying to get the car to start. Any suggestions on other carbs...
