[urq] Still running too rich.

Haven't had too much time to figure out why all of a sudden after replacing  
my thermostat, my 83 is running way too rich. I did check the spark plugs and  
found that they were all black (rich) and wet with fuel. My car has always  
started right up, but always noticed that it ran rough for a few seconds until  
excess fuel was burnt out of the cylinders. Last night I quickly hooked up  
my dwell meter and had a reading of .40 at idle when the engine was up to  
operating temp. As I mentioned earlier, I had to open air/fuel (counter  clockwise
) just for it to idle. I don't have the 4000K shut off problem. But  when 
hitting high RPMs I noticed that it does give off a bit of gas smelling  smoke. 
I'm guessing it could be the Frequency Valve (don't hear buzzing) and or  the 
water temp sensor. But wouldn't any problem with those cause the 4000k  shutoff?
