The '83 200E does not have a decompression release in the pull start itself. It's located on the top of the cylinder head on the right side. I'm not sure why the pull start on one of your 200E's has a place for a release cable. My only thought is that the pull start may have come off another model. For example, my '83 200 (not the 200E), has the decompression cable mounted to the pull start release.
