That would do it, wouldn't it? So, a bung TIG'd on the top for a fill plug and a bung TIG'd on the bottom for a petcock. Now ... There isn't any reed valve in this case. I assume one is required to prevent blow-back though the carb on the piston's down stroke? I don't have a carb ... so is there usually a reed valve in a plate between the carb and intake on these motors perhaps? 2-strokes are new to me.
