They aren't "supposed" to be loud (although a lot of old ones are).

Why not just put the correct part in and see how it works then?

It is loud but the buzz is inconsistent.  I know they are loud, but mine buzzes and then buzzes louder for a moment and then returns to its previous hum.  I wonder if sediment in the gas tank is clogging it.  This is my second post about this, but if anyone knows the score on this one please inform me.
