If the threads on the knob are stripped you can't do anything with it. Hope the threads in the housing aren't if you find a new knob. You may find one at a scrap dealer and get the complete housing to replace yours. Maybe another brand. Might have to buy reduces to make it fit.
Husky doesn't sound like a very good brand. Cheap manf. companies will run 500 K with that name and change to another name.
Did Lowe's carry that brand years ago?
