Appreciate some input on spark plug reading

If you're running at Gainesville it will get very humid during the summer months. You'll need to adjust accordingly. I ran there back in the '78-81 time frame when I stationed in Jacksonville with the Navy.
Yes - I figure it will need jetted down as temps rise. But this past Sunday was 87 deg so not exactly great air. I didn't catch the water grains but the DA was just under 2000.

And Gainesville actually does not schedule bracket racing in July and August due to the heat!
