For refueling my tank, i just take out the fuel line off the exhaust and refuel from that line. Is it bad? It's just that you must be a bit carefull when it's full because it will send fuel in the engine through the fuel line.
I don't think you can get a full tank like that, the air has no place to escape so the tank will pressurize just like when the engine is running. with the pressure and the fact that the clunk is at the bottom of the tank (or should be) all you'll end up doing is forcing any fuel you pump in right back out through the carb line.
