Have you checked the distributor fixing and the operation of the advance / retard mechanism? The poor performance and the fact it's fixed itself, but the A/R lever still makes no difference says something may be wrong in this area. It is easy for the A/R linkage to get the wrong way round. The rod should cross a line drawn between the centres of steering column and distributor, not run parallel to it. A lack of advance could explain the initial poor performance. I am assuming your distributor has not been changed for an automatic advance model so that now the lever on the steering column is just a decorative item!
