Raphael,
I understand your concern. I have had this engine for a couple of years now,and was a skeptic at first that the position of the oiler was wrong.
But I find oil in the condenser, and water in the tank of the oiler, so something seems to be working.
I did experiment at first with how many turns to open the needle valve.
---------------------
As to my build, I am now working on the layout of the RC componentsand setting up linkages.
Next I need to get the oil tube attached to the driveshaft-stuffing tube.and move on to glassing the interior of the hull.
More to come -
Thanks for reading.
