On the top of the rochester carb (63 c-10 230 engine) there is an adjusting screw . What exactly does it do and how do you set it? I believe I have the bv carb though I will try to determine that this week. I do not know the history of this panel truck as I bought it sight unseen , but , everything under the hood is original or stock as far as I can tell.
Thanks
