Fueling ajs regal raptor 125DDe 125cc petcock positioning

[freddie craven]

so i have brought this ajs regal raptor 125DDe as a cheap project for me to learn more about mechanics and to turn into more of a show bike rather than a daily rider, literally just got it and it is a mess but good for learning the mechanical stuff, gonna purchase a 125 Yamaha dragster off of my friend for my daily, what i wanted to know is what the petcock position is for off so fuel doesn't leak out of it, has a float issue with the carbs that ill fix but i just want to know what position i should leave the petcock on since it does not say off or on like other bikes

Normally 9 o-clock is off, i.e. 90deg to the right. Why not simply remove the feed to the carb and see what happens ??
