So can I move the handle forward like a 550, I am hoping to get a more positive feel for the clutch snap?

My handle does not look like the kit shown on the Ag First webpage?
 
I had the clutch adjusted with a good over center snap, and I think the problem is it slipped when running the brush hog and overheated the clutch plates. Probably have some oil in their causing some of the issues.
