Today I finally filled my hangar with smoke and made all the 
neighbors come see what the funny noise was all about.   After 
much trouble shooting, I had unraveled the following problems:

1)  The EC2 cannot share the CAS inputs with a Rocky Mountain 
Instruments engine monitor (not enough power).  Simply clipping a 
wire solved that problem for the EC2.  Thanks to Todd's pules 
divider and the tach output from the EC2 I will still be able to have 
a good signal to the RMI engine monitor as well.

2)  CAS was installed incorrectly by Atkins aviation making the 
timing about 90 deg off.

3)  My aftermarket pully seems to be marked at 5 deg ATDC and 
TDC instead of the typical 5 and 20 deg BTDC.  

Finally got it started but could only keep it running with difficulty 
until it warmed up a little.  Still ran pretty rough probably because 
the timming is still probably a little off.  Once it warmmed up some 
and I could lean it without it stopping it ran a little smoother.  It was 
just getting to the point where the EGT was warm enough to start 
using the o2 sensor when coolant started speuing into the air.

The leak is commig from where the water pump seaals with the 
engine block...  That is going to be a real hassle to fix as to get the 
water pump off I have to remove the entire engine.

There were also 2 small oil leaks.  But all problems aside, it sure 
does feel good!
