You may have the long needle version, which would explain why someone has tuned it lean on top. Take a look down the carb throat at wide open throttle and see if the low speed needle is clear of the receiver jet or still in the receiver jet. If it's still in you have the long needle carb that requires a slightly different tuning approach than a regular short needle model.
We can help you with that, no problems.
i just checked and it has the short needle in it, i ran a jp-3 and a ofna 053 with it, both pipes seemed to be shy on low end, also have kings head aluminum shoes with green and gold springs, and have it in a losi 1.0 truggy.
