I always thought that the larger gap gave a bigger spark and was better,
as long as the system generated a spark capable of jumping that
far. The gap was a compromise, big enough, but not so big that you
end up with no spark. Modern cars are more capable of reliably
handling the larger gap. As for your MG, what coil are you running?
If you have a higher voltage coil like a Lucas Sport Coil, it can
definitely handle the larger gap. The fact that it is running great
means that whatever you have, it is doing fine and I would leave it alone
as long as you don't notice any problems, like a misfire. As usual,
