Well, I adjusted a screw in the carb, the one with the spring on it. I got the truck at least to idle a little better. As it was idling tho, it started running very rough, like a lost some cylinders

My friend said I may have adjusted the mixture and got it incorrect, hence the rough idling... I ran into another issue tho, for some time the old starter has been dragging. It would eventually kick in tho. Know, it's totally stopped cranking and when I hit the foot starter all it does is bump, it won't turn over. Did the starter finally kill over you think ?
