I run an O.S.TZ and in the booklet that came with the engine, under "care & maintenance" it says "Do not inject after-run oil into the carburator as this may cause the O-rings inside the carb to deteriorate". but it DOES say to inject after-run oil into the egine itself. But I too use WD-40 to clean my engine but now I thinking twice...?
