I got a 48 Plymouth with a 218. Last night I wanted to check the timing because I kept thinking maybe there was something wrong, running like it was very retarded (no pun intended ) I loosened the distributor and removed the vacuum line from the carb. I plugged the hole in the carb to delete the vacuum leak. Started the motor (RPM around 450-500) and checked to see what was going on at the crank pulley. I couldn't see much so I shut her down and cleaned the the pulley to get a good visual of the timing marks. I started up the car again and got to work. I could see where it was set so I started to make some adjustments. After turning it CW and CCW a few times, I noticed there wasnt much or any difference in the sound of the engine. So I drastically turned the distributor CCW and CW with no audible or RPM changes...very wierd. I shut the car down and checked the vacuum advance unit. I sucked on the vacuum line and it appeared and felt like to be working good. I know its not working while timing, but sometimes you think of the darndest things. With that good I fired the motor again and messed with the distributor again with no changes. Very wierd...no sputtering or speed up of the engine rpm.... NOTHING! Any Suggestion to the issue im having? Is this normal? Im thinking I have a 'bad' distributor....weak springs maybe...I dont know...im "spitballing" at this point. Thanks for any help!
