My oil temp runs around 220 in the summer. I am told this is running on the upper edge of acceptable temps. What should I do to improve this? My cowling seals appear great (they are almost brand new). A A&P said I should move the oil cooler up a little, more in line with the air flow over the rear cylinder. How much is a little? I am going to install a spinner soon, this may help a little. Anybody have any ideas?
This is on a Smith Kit Cub, so I can really do whatever I want.
