yea let me know what goes. if the problem follows the needle I surely want to see it.
You are running the short header on your car? The head clerance , yes it needs to be around .014 total head clearance on 16%. And yess the high speed needle will be quite deep in the bore when the mixture is right.
It also could still be the motor needed to free up more but usually that creates excessive heat so thats unlikley.
