Sorry to be negative... but WHAT ABSOLUTE TWADDLE -
the spark plug gap does not affect the timing one jot - weak spark, splashy
spark, no spark, good spark, but as for when it comes, no. The fact that a
weak or poor spark might take longer to get a good burn going is another
matter. The juice either jumps the gap or it doesn't .

I think whoever said this might be thinking of the points gap, but then
thats the other way around, bigger gap advances the timing.
