Does anybody have the part number for the distributor coil on a '79 18' skier... it has a commander 351... the coil that was on it was from Napa im not sure that it was the correct one. I replaced it with another Napa coil that called for a different resistor it fired right up but idles at a lower rpm and needs to be warm to stay idling. I would like to get the verify the part number before I get another one any info would be appreciated Thanks
