As a quick check pull off the dizzy cap.

Backfire & revs rising at idle could be timing related.

It seems quite common for the rotor arm to come off and start to munch itself inside the dizzy cap, this can slowly manifest from car running rough to car dies or will not start as the rotor arm is munched to the point that no spark can be formed.

It is a 5-10 minute job so well worth checking and the dizzy woudl have been buggered with when cambelt was swapped.
