I have the same engine in my decathlon, and you are correct. It will hover, punch holes in the sky forever!! The stock tank that came with mine, looks to be @ 8 0z's. I bought a 10 oz to put in it. I'm little concerned about it setting too far below the carb. Will have to see. All I have left to do is install the fuel tank, and wing struts and it's ready to fly.
