[SEL] Cooling system bypass loops.

[David Rotigel]

Hi Curt,
	I just sent you a picture (off list) of the valve (I believe factory)  
on the 15 HP T/G IHC I used to own. It worked well to control the  
water flow and thus the engine temperature. A similar set up is on my  
11 HP Austral. What am I missing in my understanding as to why a  
simple valve anywhere in the system would not control the water flow  
and thus the cooling of your 8 HP?
	Dave
PS, Will try to send the picture of the 15 HP to slick so that others  
can see it.
PPS, Those not on both lists will wonder why in the hell it shows up  
on SLICK!
