Me too!

Have never heard a satisfactory explanation on why the eccentric cranks on some locomotives lag, and on far more locomotives, they lead.

My explanation above was not satisfactory?

The other possible reason is Walschaerts gear on slide valve cylinders. The intake ports are different, and a different motion is required.

Erik - Gary will spot it quicker than I did. It will take him 30 seconds to fix it. The guy is a genius with this stuff.
