[urq] WOT system and two way valve questions

[Newsh at aol.com]

Hi All 

I recently had a problem with my Idle switch not closing and while fixing it 
thought I'd give the whole WOT system an overhaul, the switch didn't seem t 
working as I expected it to.

I've been doing some searches and have come up with some conflicting 
information as regards the operation of the WOT switch and two way valve.
 
To clarify matters could someone please tell me for definate. 

1. With the throttle fully open is the WOT switch closed or open? 

(In other words does the "two way valve" _receive_ 12v at WOT?)

2. Which way should the check valve pass air? From black to blue or blue to 
black? 

3. Can anyone point me at a decent explanation of how that little nest of 
tubes and valves actually works?

TIA

John
