I am very nearly running my Stuart Turner Sun powered boat.
The engine is fitted with the standard displacemrnt lubricator which I will fill with Stuarts own steam oil – however I have come to the conclusion that I don’t know ‘how many turns’ to unscrew the adjuster!
It will be running on super heated steam at up to about 50 psi
I would rather have too much than too little and would set on that basis, but any guidance in its initial setting would be very welcome!
