I will try and reset the idle for warm running after I rebuild the carbs, they are quite dirty. The points cap rotor all look new but I will check the dwell and timing before I take the carbs off. Would like to get it running on the original Zenith's before considering the Webers. One other question, where is the vacuum tank on a 71 250C? It's not in the trunk perhaps behind the rear seat? The locks are not working, suspect a vacuum leak somewhere. I always was confused by the choice of vacuum locks.. I will be draining and changing the tranny fluid and filter as well. Nothing on what type of fluid to use in either the owners manual or the Haynes manual. From the forum I have read the Dextron III wold be correct. Is that OK? Or what do you all use in your Automatics?

Thanks,

Ron
