looking for the factory settings for the carb for an 86 LT250r, guy i got it from tried to adjust everything in the carb and messed it up pretty bad, it runs but VERY rich. just looking for which position the clip on the main needle is? and how many turns out on the air/fuel screw? any help would be apreciated

 

I don't have the book infront of me, but my quad is running rich, and it was set on the middle clip, as far as the air/fuel, I had to play with it until it idled, so I'm not sure where it belongs.
