Please note that the PICTURE UPLOAD function is not working. The iBoats Forum Moderators are working with the system administration folks at the parent company to get the issue resolved. This happened about a year ago and here we are again. In the meantime you can post photos as links to a picture hosting site of your choice. We are sorry about the inconvenience and will advise when the issue is resolved. Thank you for your patience.
If you are referring to the fuel/air mixture screw on the bottom carb, you have to use a long screwdriver and insert it from the outside of and through the top of the motor leg cover and trim plate of the motor leg cover directly in line with the bottom carbs mixture screw.
