Oh, and you'll need a little mechanic's angled mirror to see under the fuel bowls at the base of the carb. The way you do it is angle the mirror so you can see the gasket line at the base of the bowl and then shoot your black light so it bounces off the mirror and hits the underside. Of course, you should see
no signs of fluorescence for at least three days or more. Do it in a totally black garage and you can't miss finding the leak.
