Pardon? What he meant to say was more closed, more dwell.
The real-world way to do it is pull the distributor out and take it over to the bench, or a table or whatever so you can actually see what you are doing. Of course, mark the position of the rotor before removal. Once you get it out and ready for attention, replace the points or at least set the gap. Use dry, oil-free feeler gauges to do so. Next, make sure the vacuum advance can is intact and pulls the advance plate with vacuum applied. Next, put a couple drops of 30 weight oil on the felt pad underneath the rotor button. That is what keeps the advance plate lubed. Last, add a few drops of that same oil to the oiler on the side that lubes the upper bearing. Chrysler finally eliminated that about 1969 after they realized people were happier having to replaced a worn-out distributor than they were having to oil it. Drop the distributor back in, check the timing and you are off to the races.
