Not sure what you have in place or missing but here is a parts illustration showing the major pieces. You might check with Kanter or Max to see if either has a complete rebuild kit. If not, Max lists the bimetal spring and the outer cover on his website. Those are visible parts and maybe he has some other pieces. I didn't check all of them to see what he has. Kanter probably has some too. If the valve shaft is not seized in the bushings and is free to move that is half the battle.
If free to move, the weight and gravity should open and keep the valve open if no bimetal spring is there to close it. If the spring is present, needing to wire it open sounds like the spring is maybe misadjusted, installed incorrectly or defective.
