I did the same thing to my seagull harrier 90. I put a satio 100 on inverted,it would flood the engine, There are a lot of people that said it will work, but after many days of hell trying to start it I ended up putting the engine on right side up. Best move I made, it starts very easy now. This was when the engine was new and breaking in, very rich settings, Now that its broke in I may change it back.
