    Carb choice.

    Likely a 750 cfm. They only made two sizes 750 and 850 cfm, i dint think if any of the larger ones made it to marine applications. bottom line any qjet properly rebuilt and set up is as good a carb as anything you may put on there. Question is do you have a rebuildable core?

    How do I change engine rotation direction?

    cam,distributor, and flywheel thats it i believe. Flywheel i think you can move/ replace the ring gear for an automotive block mounted starter if you are using a manual trans, if auto you need a flexplate anyways… of course exhaust manifolds are different between marine and automotive.
