I/m rebuild the carbs as we speak on a 1980 cb750. there is something blocking the flow of gas. Start with the fuel line and at each juncture look for a blockage, a pinched line or a malfunction of that part.

There are so many things it could be. When was the last time the carbs were cleaned and or cleaned and rebuilt?
