Carb settings?

OK. Working on a Kazuma Viper that has what almost looks like a Mikuni carb instead of the standard vertical engine carb. Problem with the bike is that it only runs at half choke. I already went through all of the passages in the carb & cleaned the tank. It runs fine at top end with partial choke, but let off the choke & it's getting too much air & dies. Will idle all day long, but if you give it gas & let off, it dies. My problem lies with the two screws for air & fuel mixtures. When the carburetor is mounted, they are directly facing the frame & there is no way to adjust them. What are the factory setting for these? 1 1/2 - 2 turns out is what I'm thinking, but not sure. Any help is appreciated. Trying to think of a way to tune the screws with it running since that would be my best situation.
