  The good news is that I was able to free up the throttle, whistle,
drain, and water-fill cocks without breaking anything.  That is thanks
to WD-40, PB Blaster, a dremel, and patience, patience, patience.  The
engine runs well as in the video.

  I now want to see if I can get the water ram to work.  I can venture
guesses, but would prefer an explanation of how it works.  Does the
water go into the tiny nipple underneath (as a first question)?  A good
video showing another 364 running or any other similar setup would be
appreciated. 

Thanks,
Wayne

Here is a short video of a Steam Legend demonstrating the Water Pump.

Charlie...thanks for the video.

I hooked mine up in similar fashion and the result
was as follows.  At least the path from the ram pump
to the boiler cock into the boiler is clear.  I was
able to remove the fitting on the bottom and a small
ball bearing appeared (check valve?) but no spring
where one belonged.  I think the ram can pump, but
without the spring for the check valve no chance.
Now, I'm on the hunt for a tiny spring.  I know it
has to fit but how long should it be?  Maybe someone
has a spare or a go-to dealer for teensy tiny springs.
Anyway, a cool engine that I'm coaxing into shape!

 Wayne:

Measure the diameter of the ball bearing.  That will give you a good idea of the size of the spring you need.  Then you will just need to make an educated guess of the length.

Search "micro springs" on eBay and you should find something that will work.

Ironically, a new video was posted today of a guy operating a water pump on a Doll Steam engine.

No $%^&.  Today?  A video today? 
Somebody up there likes me.
I hope they like the engine, too.

I'll look at it now,
Wayne
