Spence – What happened to the kart?
Maxjet is only a baseline. I rarely ran what my Maxjet software spit out and would usually run the kart on the rich side especially at IMI and GJ.
It looks like the weather is going to be in the mid 70’s to low 80’s for this weekend there. I would start with a main jet in the morning of 162 with the needle on 4. For final if it warms up then you will move into 158 territory moving to needle 3 or 2.
It’s not real rocket science at this point for jet setting, just don’t lean it out too much.
