One of our comrades has a "NOISY" like a threshing machine. Noise
comes and goes , but is not related to RPM: ( hm eh ? ).
First we could use more info like type and number of pump and type
and year of engine.
I have two pumps in front of me so I know what's inside. They are completely
Question : What might make a racket ???.
2. A dry bushing at sprocket.
3. Elastomeric coupling has disintegrated. ( attacked by fuel additives)
4. Flyweights are hitting something.
5. Loose srocket.
I have a lot of trouble getting a handle on this one , because ALL noise
that I can think of , will change with RPM.
