Need help on adjustment of electric clutch on a 1720 cub cadet mower. it has the magnum kohler engine.?

i have spaced the clutch to .010 to .015 like it says in the book but it still slips and squeals when i get mowing. not all of the time but enough to make mowing aggravating.|||Are you sure that it is the clutch and not the belt? Those clutches last for years and belts only for a season or so. Especially with the noise, it sounds more like a belt. Unless you have dirt and oil in the clutch I would take a close look at the deck belt. Clutches are $2-300.00 and belts are $30 or so.
