After some searching, I have found the manual for this truck. Stock settings for the carb are 3.5 turns out from seated on the top end needle, 1 turn out from flush on the low needle and about 1mm gap in your carb opening. Click the link below for more info in the manual.

yeah, there are very few companies out there that actually want to help after the sale anymore. But, if you have any issues, we are here to help.
