May need to adjust the valves.
Backfiring would be cause by a lean pilot circuit on the decal. Or too rich of a pilot circuit will cause it on the accel.
Could be the slide plate seal. Mine does the same thing. If you turn the idle up it will start. You'll have to turn it back down when it gets hot.
