318 Engine stumble

Actually, a .045" gap should improve the spark kernal and that improves overall combustion. I would expect that to be worthwhile.

Agreed on making too many changes at a time. Change distributor and get the spark gap set up and running OK, then go back to the sync and timing.

No arguement outta me nm9,
but first is the problem of making a proper .045 gap out of a plug that comes with .035. Second is, if the new system can fire it and third is, it's a low-po combo that doesn't absolutely require that amount of pressure. I'm all for trying it later after this stutter is solved. I've been running wide gaps for 40 years or more, but not every coil will fire them and not all the time.
And finally it's just one more variable to undo, if the stutter remains. And I'm pretty sure it will remain. The current ignition is fine as witnessed in the video.
