Hey I just rebuild my 1980 carburetor and I put it back on the car, the car started up fine but the idle stays around 1300 rpm I try to adjust but the car dies? ALso I brought 3 used nikki from a Rotary shop {Judge Ito} to installed on my 80 but I notice each of the carb I brought from him it's different from my 80. I think they range from 82-84-85. ANyhow all 3 of those look very similar to each but couple of vaccum line and more than my 80. My big question is I can retro fit any to work on my 80 even though they have more vaccum line on them? Thanks, Khris
