I would invest in a timing light since you are trying to dial it in for best performance at the track, then you can also dial it back at little for the street if needed and know exactly where the timing is set at every time. A $35 light at your local parts store would be good enough for that. And then tune the carb as oldmanrick suggested.

I do have a timing light. I just haven't checked it since ive played with it at the track. I had initial timing at around 14* last I checked. But have changed it since. I will start by changing the secondary springs to lighter ones to see if opening sooner helps.

Thank you for your help everyone! I am not new to carbs, but ignorant. I spend my days with fuel injection stuff.
