Cowl Louvers
 
I checked timing, new baffling and RTV. Ill check the oil cooler again.

Installing newly primed and panted cowl louvers from Vans.

Last flight before install number 4 on climb out was 407 with OAT of about 80 degrees here in Texas.

We'll see if they make a difference. Thanks.....good informative thread!

That is well within Lycoming's limits for continuous operation, not to mention climb.

What is your CHT in cruise?

Tango Tango you have been at for 9 months. Good for you, glad you are back. There was some thread drift. As Whisky Romeo said, this CT is the normal range. I posted before but you may want to back off timing advance; it is OK to set Mags to something less than 25 degrees BTC. If you have a carb make sure the main jet is large enough. Let is know your cruise 75% power and give full rich EGT and CHT and then lean it slowly. Note how much difference EGT rises from full rich to peak, looking at first cylinder to peak. Did you check your plugs. Are they white or toasty color.
