Push button on top of new H6 carbs float bowl from Moss

[Martinld123]

I received new 1 3/4" H6 carbs from Moss to replace my old ones on my 1956 BN2 converted to M model. They look the same as my old carbs with the exception of a brass push button on top of the float bowl. Does anyone know what this is for? I will be starting up car soon and need to know what part it plays in starting or tune for engine. Thanks Marty

It's there to "bounce " the float and possibly free a stuck needle valve. A feature on early SUs. Ignore it.

Marv, thanks for information. Ignore is what I do best.
