http://brianesser.com/wp-content/uploads/2012/09/21.jpg The Bowl ***embly has an Idle Air Adjusting screw in the exploded view. When I got the boat a piece of wood was pounded in where the screw should have been. There's a plug right above it in the carb top. I can't find the screw anywhere nor do I know what it looks like to make one. Does anyone have a picture of it or know what it can be made from?
