I got the updated original Prestolite cast iron dual point (now with Pertronix) installed and she started right up. I set the timing and then adjusted the idle mixture. That took a little thinking since the carb only has a vacuum port for the distributor's ported vacuum and the car has manual brakes, so no manifold fitting either. I ended up pulling the pipe plug from the intake and installing a GM vacuum fitting (I think it's from a GM?) and routed the vacuum gauge to that so I could see what the highest reading was while adjusting mixture. I got it up to 19 inches of vaccum at 1500 rpm. I then set the idle back down to the factory 900 rpm. I think I'll leave the fitting there for the moment with a rubber cap on it, in case I need to readjust the mixture again in the near future.
