What is this article about?
Experiment demonstrates that sharpening spark plug electrodes allows a greater current gap and prevents oil fouling in car engines, though requiring more frequent gap adjustments as points burn away quicker.

Adjust Gap Distance on
Spark Plug More Often
Experiment has shown that when the electrodes of a spark plug are formed to a sharp point, and a high-tension current passed through, the gap which the current will jump may be much greater than if the ends of the electrodes are formed blunt in the usual manner. This knowledge has been used on cars which have given trouble due to the plugs fouling from the oil. After the electrodes had been sharpened, they were set to the usual gap, after which they gave no further trouble from fouling. The probable explanation of this is that the oil does not collect so readily on the small points, or that the current cuts through the oil more easily. It will be necessary to adjust the gap distance more frequently as the small points burn away quicker than the blunt points.

Sharpening spark plug electrodes increases the gap the current jumps and prevents oil fouling in cars, but requires more frequent adjustments due to quicker burning of points.
