    The vent for the HappyTime carb is in the airfilter section and is a hole near the choke nut that goes down into the float bowl.

    I had previously blocked this and drilled through to atmospheric pressure. Now that I wanted to experiment with a supercharger of sorts..., I switched it back to the vent inside the air filter.

    But when I tested it on the road, the top speed dropped from 34.5 MPH to 29. Feels like it is running rich.

    Has anyone else experimented with the float bowl vent?
