I had to take apart my truck to replace the tiger drive and after hooking everything back up it seems that I have the idle screwed up. The wheels spin even in neutral, the car moves a little bit. The idle adjustment on the controller is set to the furthest position back (no movement) but it still moves forward. Adjusting the air/fuel screw seems to slow the wheels down but when I remove the glow plug ignitor the car sputters and stalls. I've tried to adjust the screw that is on the actua throttle arm and that seems to slow or speed up th eidle, bu ***'s not the idle screw. If anyone knows what I'm talking about please let me know. Thanks a bunch.
