I have a stripped shift bar cone screw. I bought a spiral screw extractor. Bit and extractor in kit. Do I drill clockwise? What direction to turn extractor?

I wouldn't be afraid to try a screw extractor if it wasn't a Harbor Freight or similar. Before you drill it out give it several good hammer strikes downward (probably upwards in your case). If it's recessed use a trashed bolt on top of it and hold the bolt with pliers when striking it This should upset rust and grit and free it of binding. As mentioned above, heat works well to break up the rust too. Use the largest drill bit that will set inside the stripped allen head. If you have a left hand bit then use it. Sometimes they come out when drilling CC. Keep the drill rpm low and use a cobalt or titanium bit. Keep it lubed when drilling. Don't get a side load on a cobalt or titanium bit as they are brittle.
