Pair of Solex PDSIT 36-40 carbs with matched Oettinger manifolds. Standard equipment on Oettinger TSV 1800 and TSV 2000 motors. See pic of them on Oettinger 1800 motor. I bought this pair as back up during the engine build and no longer have any need for them. They are sold as seen, untested by me. They appear to be in good working order with easy movement of throttles etc. Taking best offer over £200pr
