I didn't put any type of kit in it. At the time I had no idea if or how it was going to run. I agree, it is lean on the low end, but it seems fine on the top. With the engine revved, it has plenty of power and never any coughing. It idles well too. It seems that it is lean, only at the moment of acceleration, which leads me to believe that the accelerator pump is not working. How would I know if it wasn't and what could I do about it?
