1962 235 engine. 1951 truck. Carburetor is a YF 2100s. I have the larger 3 piece oil bath with a modern paper element in it.
I get a very pronounced and a annoying whistle at almost any throttle positions except for idle and WOT. My hypothesis is that something about the air cleaner results in this noise. I need to take a test drive without the air cleaner and/or with the smaller “true” oil bath I have to test that hypothesis.
In the meantime, any guesses or pointers on where to start looking?
I’m fairly familiar with the normal sounds of a carbureted engine. This seems unique and abnormal to me.
