Got around to working with the engine yesterday. Somewhere around 2 and 2 1/2 turns, the regulator screw bottomed. I ran it at that setting and it seemed to be OK. Engine is much tamer now. About the only thing I notice is that a couple of drops of fuel come out of the carb when I shut down. And there is still some spray over the bottom of the airplane suggesting that some fuel comes from teh carb in flight. This may be normal.. I'm a new YS person (as you can probably tell)...

Question is it safe (and normal) to run with regulator closed fully, or should I send it in? TIA, Chuck
