DSX-90 V-Belt Instalation Problems

Good afternoon,

I recently replaced the V-Belt on my DSX-90. When I had it all back together, the slip clutch (not sure what the formal name is) engages far to early when the quad is at an idle, rather than at a marginal RPM. It feels a lot like a quad with a manual transmission that is stuck in 4th gear. Does anyone have any advice for me on how to adjust the clutch, or solve the problem?

Thank you,

Cris
