help trying to tighten up the slack in my chain

yeah....loosen both carrier bolts (i think they're 17mil) and then screw in the two adjusters EVENLY (i think they're 10mil)......by doing a full turn on one adjuster, then a full turn on the other. Repeat until you get the slack out and then tighten the carrier bolts back down.
 
Yuuuup . The vid I posted was just a quick one that I ran outside and did to help another member. I'll redo it with better details.
