The picture attached shows my carb without a fuel line nipple on the front of the bowl assembly. However, my repair manual and the attached diagram show a nipple assy (items 23-25) instead of the "bolt" that is on my carb. I noticed this when I removed the carb to rebuild it. Does anyone have an idea of the fuel line origin that should attach to this nipple? I bought the nipple and associated parts and plan to re-install the carb this weekend. Prior to carb removal, the motor ran very rough and only for 30-60 seconds before dying. Thanks for your input. By the way the previous owner painted the carb the gold color and installed that spring instead of the plastic connector - not me!
