1931 Dual Point Timing- Advice? in Buick - Pre War - Technical Posted October 29 Just finished reviewing all of the great information and input on the dual point distributor timing. I'm in the process of re-ringing my 32 - 50 series and replacing the cracked head courtesy of a long time member who assisted me with a replacement. Prior to starting the engine work I had gone thought the timing procedure as outlined in this thread. I always wondered if I had gotten things just right in the process. I came across a distributor from a 1933 50 series. This distributor physically is the same with the exception it is a single point unit with an 8 lobe cam. So in theory I think I was able to do away with the syncing of the second set of points. I just set the single set to the initial #1 advance mark on the flywheel and was done. I had had a 1935 40 Series and it had a single point unit and it always worked well, didn't see why the same wouldn't be true for a 32. Car seems to run as good or maybe better than when I was running the dual point unit. Not sure this would be proper etiquette for one wanting a number matching car but for a driver like mine it seems to work. Until I came across this 33 unit I often wondered if the four lobe cam could be changed to an 8 lobe and just use a single set of points in an original correct housing for a 32. This might be a little off the topic but thought I would throw it out for comment anyways.
