WANTED: Slant six Holley 1 brl carb (Preferably 1920 model)

I haven't been impressed with my 1945 model but that could be just because the previous owner really didn't take care of anything on the car. It probably isn't the model of the carb, it's probably my specific carb that's giving me issues. I'd be happy with a decent 1945 if it operates better than my old one. I've never rebuilt a carburetor before, so that's why I account for extra time during rebuild. In case I **** up haha
