    Hi guys, I'am traying to clean the sunflame 103, but I have doubt, I don´t know if the check valve of the pump has any position it seems like a screw in side of another screw

    The check valve looks O.K. If you look at the end of the pump rod you will see that the end is flat like the end of a screwdriver. To pump air into the tank, make sure the pump rod is pushed in then unscrew it two turns like you would with a Coleman lantern. When there is pressure in the tank, screw the pump clockwise to close the needle valve.
