The clutch on my barn find machine would always engage the first time when cutting grass. When it came to a water break it wouldn't engage unless I tapped it. Hopefully an adjustment has cured this. Specs call for .010 to .015 gap. Picture isthe way I found it. I tightened the four nuts till I had it at .015. Then brought it to. 011 by tightening in a circle a very little bit at a time. Hope this helps someone. I love my little Amazon hoist.
