Appreciate some input on spark plug reading

He is another piece- take it or leave it.

Not sure of the temps in FLA (lucky b you) but because they don’t deal with snow like we do- tracks run year round. But temps are cooler and air is more dense. My cars here in CT are still dealing with much cooler air than in summer. I leave alone and as they seem to be adjusted for summer air. I hope that make sense. I’d not want to melt down a piston top due to lack of fuel. A larger carb (more jet) will help your issue. See is their are any other transplants where your racing and ask them. They have already been thru this.
Good luck and keep us posted!
