Im still learning.. But I believe there isn't one..

You can loosen the pilot jet I think or tighten it..

But what your supposed to do is get new jets for the carb..

i know ur suppsoed to jet the car turn the air fuel mixture screw in the whole way and turn it out 2 turns

anyone?

it is on the bottom of your carb closest to your air box

It is the shiny brass screw at the top of picture (not the one with red arrow)
