This limits you to the few bushings you can buy plus whatever others you can turn out on your mini-lathe.

During our quest for the most flexible converted GM distributor I came up with an idea that works great. By replacing the bushing with a 4-40 setscrew, you have much greater advance range adjustment, AND you can set it anywhere you want.
