Folks

I believe my fuel servo is not delivering sufficient fuel to the engine in the 
takeoff position. Why I say this is because the difference between the peak EGT 
and the takeoff EGT is 70 degrees F on the leanest cylinder and 120 on the 
richest.  The book says this spread should be anywhere between 150 and 200 
degrees F.  Why do I care you may ask.. Well my CHTs are too high at full 
throttle takeoff.  I have to work to keep them below 430.  I have done 
everything possible to maximize cooling airflow with little improvement in the 
CHT situation.  

Anyhow, I would be interested in information from the group on the following 

Like to compare fuel flows at full throttle at close to sea level (mine is 
between 15 and 16 gals/hr)
Any info concerning experience with enriching the takeoff flow on the bendix 
style RSA-5AD1 servo (this setting is internal, I have found no reference 
material on the procedure)

Thanks

Tom
