The new carby came to day. It came with 3 gaskets and a mounting plate all hermetically sealed in the packing. The carby looks the same but doesn't have the un-burnt gas return that the old one has. Difficult to line everything up and fit but eventually did OK. It now runs fine. The only bitch is that the primer circuit needs a bit of work. It will start OK but needs a few pulls to do so. Otherwise I am very happy with the repair.
