I purchased a YS 91 AC. It is supposed to have a new diaphram and gasket set. It will not run properly. You can actually drive the high speed needle all the way in and the engine will not die. I have never had a glow engine act like this. Does anyone know about this engine? I have never had a YS. I started at the factory settings for the low and high. 1 1/2 turns out on each. It will start at that point but not run right. As I mentioned something doesnt seem right with the high needle. Also there is an O-ring near the carb that seems to be leaking fuel.
Any advice would be appreciated.
Thanks
