The guy i bought this 81 rabbit from said he adjusted the injector pump (full load adjustment screw?) so he could blow smoke, (whyyy?)but he may have been just blowing smoke up my a**. I've been blowing black smoke as i accelerate from third fourth and fifth, especially in 5th on the highway, and i only get 31 mpg. I turned the adjustment screw down and the idle up and have been playing with that, plus i checked the timing and the pump timing was within tolerance at about .920mm. I went ahead and advanced it to 1mm. I haven't taken it out on the highway, or checked the milage yet, but i was wondering where to adjust that full load screw to with the idle screw to get it to optimal without the guess work. Also any other reasons my milage is so bad would be helpfull, thank you all, bye
