priming the 2E carb is a must before starting. no electronic controls just an accelerator cable. E10 only made it worse. also the fuel pump is mechanical and the engine has to be running for gasoline to flow to the carb. different from the gli that is fuel injected with an electric fuel pump that starts to pump the moment you turn the ignition on. before the fuel injected systems, electric fuel pumps provided better pressure thru the fuel lines for twin carb set ups.
