Thank you. It's us fools who poured water. And so it stood in the pantry for at least 10 years with us.
In general, age is not determined. Maybe a hundred years ...

For some reason, my motor did not spin. It did not work. Without water. with water also.
What am I doing wrong?

Valves and easy motion are critical ...check Valves Cycle and "seal" with no binding .

Grum and Temporal are master builders ...As pointed out above  not a lot of power output so Binding will cause stall ..[no cycle]
nice looking machine BTW
Some in forum have posted that Stirling Cycle engines are running on Night sky/ and ambient heat from earth//huge area of potential for FE .

If you remove the connecting rod from the crankpin and push the power piston down you should feel some compression (quite light) and should not hear air pissing out past the powerpiston and its cylinder - or leaking from the valve you have found/show in your sketch - or leaking from where the heat tube attaches to the main casting - or leaking at the displacer rod slide. And the displacer must be sealed itself on the rod and not rubbing on the heat tube. They are fussy.

The valve should open when you pull up and seal tight when you push down.

You could use dish soapy water to see the leaks as well or even motor oil.

Hi Kolbacict.

Your engine is " air cooled " no water involved, none!!

Firstly, the two pistons, power and displacer need to be at 90 degrees to each other. Is the flywheel
" keyed " onto the crankshaft so that this 90 degree relationship is maintained?

This engine will only run in one direction so you will have to find that out by trying in each direction.

In your sketch I can see a valve in the bottom of the power piston, this needs to be shut perfectly. This might be the cause of the engine not running, however this engine will need a reasonable amount of heat to run. What are you using to heat the bottom of the displacer cylinder?

Whilst the engine is cold you should be able to feel a sort of pressure and suction event over a revolution. If this isn't the case then you have air entering the " closed " system.

That valve in the bottom of the power piston is called a " snifter " and is used to replenish system  losses but is a rather " uncommon " fixture.

Cheers Graham.
