[700rpm]

As someone here said (Tom W?), "Test, then replace." If you just start throwing parts and money at the car, it can quickly add up, a $1000 in this case, when all he needed was a 5-cent washer. I think this often happens because a guy (I'm not saying this guy) is inexperienced with mechanics or the Model A, panics, and applies a modern attitude toward the problem. A deep breath, patience, some reading, and some close analysis and testing can in most cases sniff out the trouble, and you gain a little more confidence in the car and your abilities to fix it every time you take that approach.

Ward, thanks for the pictures and the explanation.
