I am working on a Kawasaki GA1400A Generator Code # GAT 40A-BS00. When I removed the carburetor to clean it I removed the main jet from the carb and tried to use a twist tie wire to clean the small openings in the jet. The holes are plugged tight, I have soaked for a couple of days in carb dip cleaner. When I look into the small holes in the main jet it looks like I am hitting metal. The tie wire will not go to the center of the jet to open the hole. Has anyone run across this on a Kawasaki generator before? Are the holes not supposed to be open to the center of the jet? Thanks for any help you can give me.
