If this problem occur on one rotor only I would check the secondary fuel in= jectors delivery rate. If one deliver more fuel than the other, one rotor = will run leaner. Then, you probably cannot tell by the o2 sensor readings.

Hmmmm?  Good point.  I was running lean at times= since I was getting it to start better having it lean.

Hi Chris,
 
I lost a rear iron from detonation whe= n I first started experimenting with a turbo 13b.  The main reason was= a lean mixture.
The formula for detonation is: high in= take manifold pressure, high intake air temperature and a lean mixture= .
I would never go over 30" intake = manifold pressure before I know for sure that the mixture is NOT lean over = the full spectrum -- from idle to full power.  One way is to watc= h the manifold pressure as you open the throttle and limit it to 30".  Do not open to full throttle until you know yo= u do not have a lean mixture spot.
 
If this problem occur on one rotor onl= y I would check the secondary fuel injectors delivery rate.  If one&nb= sp;deliver more fuel than the other, one rotor will run leaner.  Then,= you probably cannot tell by the o2 sensor readings.

Chris,

Well, at least this will be an inexpensive repair, but any idea what c= aused the springs to flatten out like that?
