flow direction in slingshot manifold

[john in illinois]

Thanks for the inside pics . I did not remember the inside design when I put it together.
The carbs do empty into a plenum ,but they do each flow to one end. I had clean plugs in the front and rich black plugs on rear. I have since adjusted float level and a leaking power valve and plugs are the same.

Both carbs will feed both the front and rear cylinders. The divider would need to extend down into the lower manifold in order to make it so that the carbs only flow to their respective ends of the engine.

If you didn't already, you need to clean the plugs before you evaluate it being too rich, since once a plug gets black, it takes for ever for it to go away even when running the correct mixture.
