I thought I had it figured out. I have the original owners manual and I followed the instructions and in adjusting the chain I ended up twisting off and breaking both of the chain adjusters! They had back up nuts on the back side, I didn't know this!! Anyway, what do I do with the nuts to make the axle go backwards to tighten up the chain? Any help would be great! Thanks!

 

Bump, I really need help on this!
