Plug fires when the points open. Therefore widening the gap advances the timing.
Most points are set at .015". I have an 032 on the bench that runs a touch better set at a tight .020".
I have several nasty 'biters'. Mostly the problem of a lean fuel mix when cold. I leave the ignition off, set the choke and pull it over two or three times. Set the choke at 1/2, flip the switch and pull like you mean it.
Less danger of hyper extended fingers.
