My warrior is running like crap,it will run great if you put a new plug in it but if you shut it off it wont start back up.I thought it was the parking brake so i put a brake block off on and unpluged the sensor,i thought it was the carb so i took it apart and it looked fine,i also took the gas tank off and flushed and cleaned it but it still wont start up on a used plug.The starter clutch rattles or clunks when you try to start it could that be my problem.It dont make any sense to me why it will run fine on a new plug but thats it. PLEASE HELP

 

sounds like you might have bad spark look at the coil and you voltage, might not be firing right.
