Ughhh I need help. Tuning issues.

Yeah the car is running lean in the colder, thicker air. I would fatten up the primary jets and use a larger accelerator pump squirter. The pump squirter should take care of the stumble when you hit the throttle.

I still think that is a pretty small cam to be locked out at 34 degrees. But it would want probably 20-24 degrees initial and then maybe the 34 total.
