Obviously by enriching mixture your motor will run a bit cooler, but you are loosing some power, keep it in mind. I don't know your settings, but at this time of the year motor shouldn't be running hot. Do you have a temp gage? or any way to monitor engine temp? Ideally to run 220-230 for air cooled motor. Make sure to warm it up to 180 before rolling of the grid. If it runs to cool you can tape the oil cooler. By removing the tape strips you can keep the right temp as an air get warmer...
