    This Dolmar has been beating me up for a while now.
    I think after some carb tweaks I finally have it.
    It still needs rings (.016" and .022" gaps)
    But if it continues to run fine, I will replace them with crank seals.

    Is that open port or closed?

    Interesting ports. It appears that the top of the transfer port is convex. That is, that it is sloped at the back and then slightly angled down as it approaches the port opening. Correct me if I'm wrong. - If so, that would give a more flatter flow into the cylinder than a flat roof on an open transfer.

    It is also shifting the flow towards the back of the cylinder by the slight curve in the port.

    It shows a lot more thought than the straight 'industrial' ports on some of the other open port designs.
