84 RX7
Fuel bowl drains in about 2 or 3 minutes after car starts. Car starts easy. Have replaced carburator, fuel pump, fuel filter, all valves in fuel return line. I bipassed the gas tank, ignition timing is right on, but nothing I do seems to make any difference. I can't find any vacuum leaks. Any ideas out there on something else that could cause the fuel bowl in the carburator to drain causing the car to die?
Thanks for any help!

 

Check the float level, if it's set too low the engine will use the fuel faster than the pump can pump it in.

 

Thanks for the response. I think my float is probably set a little low, but it appears I found the main source of my problem. I replaced the purge valve and the carburator is now holding level. The car still dies, but I probably just need to fine tune the fuel system.
Thanks again
