The only thought I have is to be sure you open the throttle, put your finger over the carb intake and draw fuel into the fuel line and carb with about three turns of the prop. Then close the throttle to your starting position (1/3 open ?), flip the prop a few times to distribute the fuel, hook up the glow driver and flip to start. If there's fuel in the engine, the start should be independent of the needle position. If the needle is set to lean, the engine should still start and run for a few seconds and then die. But it should start.
