i have a feeling there is a reason they have not been snapped up. i would guess it probably has something to do with them being old or od. is that 1 powered by a vertical shaft engine or am i missing something? the one with the vertical shaft engine looks like it is at least the newest out of all of those machines. might be worth getting the model numbers and see what parts availability is like. i think someone was on here not too long ago looking for a carb for a machine like that and they are not very common or easy to find which could result in it being expensive when you do find one if it needs one.
