    Looking ahead a bit but I'm struggling to find all the vacuum ports to connect the trusty Morgan Carbtune up to. Does anyone have a picture or line diagram showing where all the ports are exactly.
    I've tried searching online and all the advice and tutorials on how to do it skip the vital step of pointing out where the ports are.
    Thanks in advance for any help given.

    Cylinders 2 and 3 have a nipple easy to find. Cylinder 1 (left) has the petcock vacuum hose attached to the nipple. Cylinder 4 (right) has a bolt on the right side of the engine (not showing on the photo). You need to remove the bolt and attach one of the copper nipples that come with your kit.
