So I just got my jp premium and fired it up put like 20 plays on it and have noticed the mouth doesn’t open. When testing it in diag I hear and feel something at the jaw but nothing happens. I pulled the head off and noticed markings of a washer on back of metal plate and screw hole on coil. Am I missing a bolt? Sucks I just want this dang thing to work any ideas or help I would appreciate....pointing with small screwdriver in pictures thanks again
