Well, this is my mistake really. I tightened my clutch, backed the nut off a bit, like it says in the manual. My truck worked great for a minute, then it made a whine noise and stopped going, engine still turns wheels won't. My plastic gear on the drive shaft is tore up. I tried to remesh it with the metal gear comming off the motor, but when I hit the accelerator the gears still don't mesh.

So was this a problem with the clutch being to tight or a bad gear mesh? I'd imagine it was the clutch 'cuz I was digging trenches in the dirt before it died. I ordered a new plastic gear, should I be ordering new clutch parts as well. And can somebody point me to a good tutorial on how to adjust the clutch AND check to see if it's not too tight before I destroy another gear...

Thanks.
