About how much carbon monoxide is produced in these two different reations?
About the best that can done is simply to look at the ratio of carbon in the two cartridges. 


  
    $\dfrac{56.7*0.09}{144.6*0.28} = 12.6$%
  


The ratio of carbon dioxide to carbon monoxide formed on burning would depend on particle size, how well mixed an so on. The second formulation with sulfur is akin to black gun powder. The sulfur burns first at a lower temperature to ignite the charcoal. The sulfur dioxide would be toxic as well, but not as fast acting as carbon monoxide.
