alright, i'm going to do this saturday. it's got to either be the pump or choke. the filter is almost new, unless there is another besides the one in the carb. just thinking ahead if it was the pump, would an 85 have a mechanical or an electric in-tank? can you just swap out chokes or do you have to replace the whole carb? i have an electric choke and the light does come on in the cluster, but that probably doesn't mean a whole lot.
i have an 85 k10 with a 350, BTW.
