Yes it is.
With the close gap, both sets of points are closed longer and there is a voltage drop. In that state, the coils do not charge properly.
The spark to the rear cylinder is lost. Open the gap a bit and away you go.
I discovered this at about 400 miles from home. At the same time I learned about the Daichi "upgrade".
After that I cornered the world market on NOS Lucas points, no more problems.
That was at least 40,000 miles ago and the same Lucas points are still in place.
