Post a pic of the valve.
On some of them you have to press them down to light the pilot and then slowly release them and find a notch which lets you go further to ON. Maybe you have to just wiggle it and find that notch.
On old stiff ones you may have to pull it up slightly to find that notch. The grease inside the valve around the valve stem/packing gets stiff and then the knob gets stiff to move.
