Shifting problems

I know there are threads up here about this and I have read all I can find. I spaced mine like one of the links and that helped alot. What I want to know is whether or not the Primary clutch(the one on the bottom on mine, 2014 Sportsman 850 XP) should retract all the way when I go back to idle. On mine,when I rev it up the primary,of course, goes in and comes back at idle but only comes all the way back out if you cut it off. It comes out almost all the way out. Just stays about 1/8 of an inch in. As soon as I cut it off it comes all the way out. When I spaced the secondary(on top) it started shifting alot easier but it would some times before until I rode it hard and then it would become impossible to shift until I cut it off. I rode it a little and it didn’t get hard to shift but I am worried that it isn’t retracting all the way back out. The belt seems to stop at idle but I don’t know if it will after a hard ride. Advice??
