Unless the fuel return didn't function properly (can you preflight it?),
in which case you have zip.

Owning one of these planes that Oval mentioned (pressure carbed E-225
powered Bonanza), I doubt you could even get it started if the fuel return
wasn't working. It's sort of like asking if you can start the plane
without the magnetos.
