So finally I found it. The clutch operating lever that the clutch cable attaches to pulls the clutch bolt in and out. Mine was going all over the place when you squeezed the clutch handle, and the wiggling side to side was causing the clutch bolt to get trapped in the hole in the lever, so it couldn't release. I decided the spring was too tight and forcing it all over the place. I was wrong. It was too loose, so twisting the hex casing on the end of the cable on the left of the pic firmed up the spring and the clutch operating lever now went straight back and forth. I wish iI'd checked that before I pulled all the other stuff apart trying to find the cause. The simplest cause is usually the cause..
