    I feel really dumb asking this but the idle on my motor is a bit high and was just wondering which screw do I adjust? /forums/images/graemlins/crazy.gif Is it the one on the front of the carb on the one on the side? If its the one on the side then I don't get it because it doesn't actually touch the throtle bracket thingy(?) its backed out so far.

    P.S. ---- I was also wondering, should I be replacing my auto hubs on my 10 bolt with manuals? How hard of a swap is it and do I need any special tools? I've never opened up an axle b4. Thanks.

    If the screw on the drivers side isn' touching your throttle bracket then you either need some throttle return springs or have something wrong!

    Manual hubs I believe are cnsidered to be stronger(a little).. The main benefit is that you dont have to worry if the auto are goign to engage or not. My old ones had a tendency to unlock when I needed them!

    If it's not touching, it's probably the fast idle? On mine the fast idle is on the left side and only matters when the choke is engage. The normal idle screw is on the right side (facing the truck from the front that is), kinda down low, not real easy to see. This should definitely be touching something and you should hear the difference as you turn it.
