I need to adjust the valves on a B. For the life of me I cannot loosen the nut on the screw. I don't want to reef on them to much. Any tips?

Heat with propane torch to 500ºF, apply bees wax candle to threads, near nut.  let cool, and tru tightening, then loosening, alternately.  repeat, as necessary...Wink
