It's the other way round, John. If lifting the pin only drops the rpm, then
the mixture is too lean. The backfiring is also a symptom of being too
lean.
Unscrew the mixture nuts by 2-3 flats and check again, I think you'll find
it's better.
If it was too rich, then lifting the pin would cause the engine rpm to rise
and stay up. Ideal of course is when it rises a bit and then falls back to
where it was.
