Thanks for the reply.
The gremlin I'm chasing is low end power fluctuations. At times it pulls what 
feels normal, and is a pleasure to drive. Other times it is very slow and 
sluggish. Full throttle is good. The crackle is usually in direct correlation 
to the other behavior. At times it has even had slight hesitations (not a 
misfire) at 1/2 throttle acceleration.
If there is a constant, it is that as I turn the mixture screw CCW (giving 
higher DC readings) the low end seems better but the crackle is obnoxious. If 
I turn it CW (lower DC readings) the crackle disappears, but it is a dog to 
get going. Is the latter an indication of lean running, or is the higher DC 
number showing lean?
It is confusing to me from the stand point of discussions stating that a 
reading of 4.6 indicates a rich condition, AND that the ECU is trying to 
richen the mixture. Those are opposite situations. In other words, what ever 
the DC is trying to do means the engine is experiencing the opposite. Right?
Carburetors were soooo easy. I guess it must be a labor of love.
Thanks for all the help.
