I just discovered that the nozzle on my front SU is loose. This is the fuel feed nozzle on the bottom, please see attached photo and illustration.

It's loose, as in I can rotate it with my fingers, to the limits of the two attachments. Since the mixture adjustment nut is right there, I'm hesitant to try tightening things before I know what I'm doing. What can I do to get this thing tight? These are 4-screw SUs, btw.

Thanks in advance for any and all help.

Those nozzles aren't supposed to be tight. If theyare tight the chokes won'r work and the only time you need to worry about stopping fuel leakage is when you floats are too high.

Thanks, Bruce. I appreciate that. Had no idea.
