Another Carb Leaking Gas was created by Triumphcubguy

My 74' 250 Enduro is leaking gas from the overflow under the bowl. I have set the float level by measuring from the gasket surface to the float arm according to the manual (Duel float model).. No debris under the needle and stops fuel flow with light pressure.
I am thinking the needle is jamming when I replace the bowl because it does not have the wire retainer pictured in the manual. I have tried several float settings but gas continues a steady flow from the overflow. Am I on the right tract?

Jamming may be a possibility. You could try tapping the carb while its on the bike with the back of a screwdriver to see if that helps un-jam the needle and stop leaking. It could also be bad floats. Have you checked to make sure they're actually floating?

Checked all that, even turned the carb upside down and shook it but no dice. Ordered the needle & seat with the retainer. Will try that. Thanks.
