I'm trying to engage the overload spring, I've tryed putting the screw driver bit through the hole in part but there is no way I can flip it over. I'm looking at the owners manual and itsays something about a spring block tool, spark plug socket and screwdriver. I guess I'm not doing it right I'll look for that "U" shaped tool and give it another try. Thanks for your help!Check your tool box....you should have a tool/fixture that's shaped like a "U" with a hole to run your screwdriver thru. Place the overload spring tool on the block (you will see how it fits when your down there) and slowly turn the block down to release the overload. Careful as the overload spring has a lot of pressure on it when released.
P.S. You might want to tip your sled on it's side when doing this....it takes a lot of pressure off the spring![/b]
