I guess I just figured that if this is the biggest I can go on this carb, then a slightly larger carb would allow me more "play" as it were. Truck stills a bit sluggish, but I think that may have more to do with how I have the TV cable set... there is still a good 1/4 inch of "play" / run when the throttle is at WOT. But I feel like if I pull more TV cable then my start off of idle will be drastically changed... and I've already turned the line pressure up 1 1/2 turns. Also I know for a fact this is the wrong cable as it came off an A500, and this is an A518 46RH. I may just split the difference in the cable and see how it acts.
