Default Does this look OK for cooling?
Here are some pics of my setup. Wondering what I can do to cool the motor a little more. I'm still getting temps around 220-225 after I taxi back and shut down (measured with Raytek gun and the "spit" method). I am burning 93 octane with 32:1 H1R oil. 2.5 gallons on the motor. Walbro carb, needles at L7/8 and H1.5. Getting around 6200 RPM with a Bambula 26x8 prop. Sounds rich in flight.

I would like to know what else I can do to lower temps. Retard the timing more? It's set at 6mm.

Thanks.

BTW... my RPMs went from 5,600 RPM with the Bisson Pitts to 6,200 with the Supersonic Pitts... WOW!!!
