Make sure your engine is a 47 engine and factory type distributor. If you have a later 8BA type engine swapped in then you must use a matching 8BA type carburetor with the vacuum port in the center section to run the vacuum advance diaphragm. Post a picture of your engine and we can make sure the parts you are putting together will work properly together.
I encourage you to try rebuilding a Holley carburetor yourself. You don't need any special tools, other than something to soak the parts in. Like GB I have used Berryman's carb dip, but I hear good things about ultasonic cleaners being used for carb parts cleaning too.
Go to your local swap meets and get a spare carburetor or two (or dozen... they multiply), they should be cheap. I don't pay more than $20 for a core and don't buy anything rusted stuck. Be aware of the multiple versions produced over the years. You can mix & match to a great extent, but need to keep the guts as an assembly (spary nozzles, air tubes, hold downs).
Have you asked the shop that swapped out your carb if they still have the original? If so, get it back and try rebuilding it.
