Mr. Eagle's reply #12 still has tons of merit in that if we had a universal mechanical sound vocabulary that exactly describes the onomatopoeia, many could describe exactly what they hear where this problem could be narrowed as to exactly what needs investigation.

Many of all of us have experienced that Model A engine noises are similar to different musical notes on instruments in that after a few years we become familiar with these many unique different Model A noises such as:

1. "Thump, Thump, Thump", similar to a low note on a bass guitar; or,

2. a much higher note of a "ping, Ping. Ping", similar to striking strings behind the bridge of a mandolin; or,

3. a "Click, Click, Click", similar to similar to hitting (2) hardwood drum sticks together; or,

4. any combination of different sounds with or without a rattling effect, or having a certain rhythm with different intonations.

5. After a few years many Model A owner's ears become familiar with this Model A music.

It is often beneficial to have a neighborhood, experienced Model A mechanic neighbor to listen to what combinations of sounds are eminent in order to "quickly" determine exactly what needs investigation.

Then one has to be careful that some neighbors cannot tell the difference between a Waltz and a Two-step; and worse yet, cannot even dance. LOL
