Hi BigMustafa,your wish is not so hard to do as you can think.Only you will need a separate room to open window for a long time in winterdays.I did this several times and I think you can too. Mount your engine firmly on a bench and take your bench to that room.Put a garden hose suitable to exhaust outlet and put other end into a about 5 liters pet bottle or similiar container,quarter full of water. (garden hose will go thru the tight fit hole on tap).Open some discharge holes upper end of the bottle to let exhaust gas go. Open the window,Now ready to run.Good luck.(Oil will be kept by water and bottle and only exhaust gasses will be discharge thru holes of upper end.
