Adrian,
If you haven't already done this, get a vacuum gauge (inexpensive) and
hook it up to manifold vacuum. While idling, note what the gauge does
and advise the list. Rev it up so that the backfiring begins and note
the gauge action. (When you buy a gauge, it will usually come with a
printed guide to troubleshooting - most useful.)
