I got to the race today and was called to the gate and my son's quad was locked up but the funny thing is you can push start it and it will run fine but as soon as you stop it stalls like the clutch is locked up so I took the cover off where the clutch is and the pads do not look like they are engaged but you turn the tires and it turns the motor over any ideas on what it may be also is the large thin nut that holds the clutch on left hand threads or right lastly is there any after market hop up clutch for the quad thank you I need help with this his last race is the 23rd so I need to get something going
