Two solutions now that we know it's a Holley.

1. Lower float level to bottom of sight plug. If already there, lower a tiny bit farther.

2. Connect the two vent tubes with a rubber tube and cut a couple of holes in the top of the tube so air can still vent.

One or both will cure the problem.

And tell the kid it is OK not to lay down rubber when he stops!
