No direct experience, but have worried on this bit conceptually.
Maybe the charcoal has no syngas left to give? Seems to me charcoal made to fuel a gasifier should come with more BTU's left per unit volume than more-heat-distilled charcoal made for not-fuel uses, like feedstock for activated carbon, or adding to animal feed. Can you get more-assuredly gasifier fuel charcoal??
Per often repeated internet advice:
Don't use wood gas to fuel an internal combustion engine prior to taking the precautions needed to avoid seizing up the engine due to tar.
