When an engine backfires aka (burps) back through the carburetor this usually indicates a lean fuel to air mixture or an intake leak( which is more noticable at low RPM). When the an engine afterfires, aka (farts) out the tailpipe it usually means too rich of a mixture or unburnt fuel is entering the exhaust system
