    underneath the card there is a small screw that should have a spring on it for tension, not on the side where the throttle is up right underneath where you put the air filter on, this is the idle air control screw. By turning this the idle will go up or down, u want it to go down so I belive you screw it in to do that, or possible the other way just try it once and see, youll be able to tell if the opening in the carb gets alittle bigger or smaller, if it goes smaller the idle will be less and vise versa

    i just tried to adjust the needles what should the low end be set at for the winter. when ever i try to make it idle and sit there it died. when i run there is a good amount of smoke comming out.

    if it is lean then there won't be to much smoke because the engins is burning less fuel so I think it might be rich

    if you want to just bash your truck and have fun do what i did to my mt2
    first put then low end flush with the carb then when you have it set let it idel if it dies right away that means that you srewed in your idel control srew to much and you should lousen it but rember make the low end flush with the carb then when you get use to it and want to get more low end then screw it in a bit and you should see a difference
