This^^^ I would never recommend a locked out distributor when using a stock or stock type distributor. I’ve been running my distributors with 18-20 degrees mechanical advance and all in by 2000 rpm for 25 years. The reward is no hard starting, no kickbacks, no broken flexplate teeth and no broken starter drives. Spins over like the plugs are out.

We class racers use an MSD timing control with fixed distributor. It'll take 15* or so out for starting. Also , we class racers sometimes use it to retard the timing in high gear.
