Need a good bowl for an NH straight through carburetor. This is the type with an offset drain. The diameter where it fits the carburetor is 2 7/8"'and the bottom hole is 9/16"
In case you canít find one: I think you may be able to file a notch in the bottom of the housing to match the later NH (so gas is drawn from the bottom thru the drain body) and use the later drain & bowl.
Sent you a PM this morning.
