re 20/25 HP- Tank Engine.

This is to confirm that you are making tests with a standard 20/25 Car inclined at an angle of 1 in 3 both in a forward and reverse direction with a view to examining the effect on the carburetter, and the dipping of the slipper flywheel in the oil when tilted forward.

We are also anxious to know in the latter case whether a steam pocket is likely to form at the back end of the cylinder block.

It is assumed that the radiator cap with a 2 lb per sq. inch loaded valve will be used on the radiator.
