Used, untested Rochester carburetor. Removed from a 1985 Chevy S10 2.8L V6 4x4 I bought for parts years ago. I also have lots of other OE parts from that same truck (both axles, driveshafts, leaf springs, calipers, master cylinder, water pump, PS pump, alternator, fender flares, left front fender, grille, taillights, gauges, radio, etc.) Will consider offers on any or all.
