Hello, Have a 1982 johnson energy wood stove. Just bought it. Taking it apart and cleaning and painting it. The damper control seems to be bo jacked. Turn it one way and its wide open and turn it down to closed position and its still open alittle. The stainless plate is bent on one corner. Bend the plate down to the bottom damper will close but turn it the other way its not wide open. Any assistance will help. any online manuals to look at ? Any where to buy spare parts? Thanks
