If you installed a new cone clutch, the angle of the linings may not be an exact match to the brake ring and annulus and it will stick when applied. A good swift rap (or two or three) on the exterior of the brake ring with a dead blow hammer will release the clutch. Had this happen with Henry Frye's race car at Summit Point a few years ago. Driving around the paddock with the gearbox cover off and excersising the OD, releasing it with the dead blow hammer. It eventually worked it's way in with time.
