mywifesquad - you are correct about the other being a brass plug. I have been all over this carb and there is no other external adjustment.
Thinking about the four things a engine needs to fire (Gas, Air, Compression and spark) I decided to focus on the air cleaner as every thing else was present. It did not look dirty from the outside and i didn't notice the oil till i removed it. Upon removing the crankcase vent tube I accidentally half tore off the airfilters metal top. I then cleaned the airfilter with brake cleaner and JB welded the top back on (remember it had oil in it from the crankcase vent tube after rolling over) reinstalled and adjusted the air/fuel mixture to increase the idle speed a tad and bing no more sputtering during acceleration.
These carbs seem very sensitive to everything so don't do like i did and overlook the obvious.
