Yerf Dog 3206 Belt Replacement Issues

[jcjohnson72]

I recently replaced the belt drive on my Yerf Dog 3206. Since doing so when I start the buggy it tries to take off instead of sitting still while idling. Once you give it gas it has hardly any torque and is very slow to get up to speed. When you turn corners it just about stops. The belt seems really tight. I checked the manual and it shows the belt I got is the one that supposed to be for the unit. Not sure what to check next. Here is a video http://www.youtube.com/watch?v=6d998e2O-ec and some pictures.

Can't really tell in the video by the clutch wheel is kind of jerking back and forth not operating smoothly.
