Chris, I had experienced some of the same surging problems that you must be having. 
I can only assume that anybody with a 162 on Fadec equipped ship probably 
also are having surging.  My brother and I took the time to cut one of the 
two wires on the temp censor and run a wire up to the overhead switch panel 
to disconnect the circuit during startup.  The process did not take very much 
time and have proven itself to us to be a complete success.  There is no way 
you could mistakenly not reconnect the circut because the yellow error light 
on your dash will be glowing at you.

Regards,
Brett

Brett, Very Interesting! I never thought of that!
you didn't say exactly what is startup like without the sensor on?
Any other "side effects"?
Thanx,

I've only started my engine a few times but it always holds steady at
about 1800 RPM immediately after starting.
How did you guys zero in on the temp sensor having something to do with
the surging?

Chris, After initial installation of the Ez start clutch we were experiencing bad
surging during start up.  Sometimes the surging was so severe that when you 
would begin to engage the clutch the engine would immediately stall.  
Engaging the clutch takes small movements as you probably know and having the 
engine surging makes a smooth transition very difficult.  Now that I can 
break the circuit the startups are as smooth as can be.  Once the engine is 
running stable I just begin engaging the clutch as usual.  After the clutch 
is fully engaged I just reach up and flip the toggle switch and reconnect the 
circuit.  Then you will have to push the reset button on the fadec to 
deactivate the yellow error light.  This problem seems to apply only to ships 
with the ez start.  Apparently somehow the censor tells the fadec that the 
engine is cold and the fadec responds to this input.  Because the is no load 
on the engine it begins to surge.  The fix was a cinch.  The ez start was the 
second greatest improvement to our ship after the cog belt.  Makes those cold 
morning starts much easier. All I had to do was work out a little bug.  I am 
not sure how many ships are experiencing this problem.  Have not heard to 
much of the problem.  Lets face it, there are no two RotorWay's alike.

I talked to John Spurling about the problem and he gave me the info on what 
may help to resolve the problem.  However I do not know where he received 
this info.  All I no is he was very correct.
