Bernie, thanks for your perseverance: Timing bit off and combined with dist. cap carbon brush failure, old points, and some dirt in carb bowl, probably all contributed. Got going on new fuel, and changed back to the 1/2 tank + of existing tank fuel and still fine. (saves draining off). Now a seized OSF brake (off not on), so one hell of a pull to the NS to resolve.
