EIWI Table engine.
This engine ran very smoothly at scale speed when it arrived from Poland.
The push-on hose tail screwed into the spool valve chest spoiled the look of the engine. New pipework, using thick-walled brass tube and pre-threaded cast bronze elbows was made up. A speed regulator valve, and an 1/8" BSP adapter was fitted to accept an 1/8" BSP airbrush hose.
A 4mm i/d "O" sealing ring was fitted to the spool valve rod gland to give a better seal. The driving piston rod gland was already fitted with an "O" sealing ring.
Many thanks to MacIej Izdebski (engine501) in Poland for making this very attractive engine available to me.
