my friend has a blaster and is having trouble with it. Its a 1999 blaster and he would like to know what are the symptoms of a bad throttle switch. He has tried to re-jet it but it seems to run worse. The fuel mixture has been played with and nothing seems to work. The plug is fine. Any suggestions would be appreciated. thank you

 

unplug the two tors connectors one is connected the th throttle the other is above the carb hooked to the cap, see if that helps
