Anyone know how to ID a carb with the choke milled off? I think that is what is going on here, cant find any number except GR 3752 b on the top of the main body. Primary metering block has 10569, and secondary has 11166. I am thinking they are around 800 or 850's, but cant find any of those #'s in the holley book.
