more than likely not a result of the manifold adjustment at all but put the screw back to flush and try to fire..if it only "puffs" what your experiencing is bolt stick, more than likely you have an o-ring thats fitting too tight on your assembly..
...typically the third inner can o-ring will cause this
-is your f/t screw removed?
-bolt cleaned and lubed?
if yes to both of those replace the third inner firing can o-ring and the bolt sail o-ring "o-ring in the rear hatch..you have to remove the firing chamber to get to it"
