there is another plug on that same wiring harness. it has a green connector and the wire is white. where does it go? will it affect the carb operation?

I'm pretty sure the one you speak of goes to the carb cooling fan sensor on the intake manifold.

any pictures where it goes?
Are you talking about the green plug that is physically mounted on the carb? That is for the fuel cutoff solenoid. It should have two wires, although some people directly ground the ground wire so it never cuts off the fuel.
Other than that, I agree with PAFJ, as i think the cooling fan sensor has just one wire. It is not connected to the carb, but it may be part of the same harness. i can't recall what color the plug is.

If you are talking about this roasted and toasted single wire, it is for the carb cooling fan and is attached to a sensor on a little piece of metal on the exhaust manifold.
If you are talking about what appears as one big wire that is actually two small ones in a sheath on the carb, it is for the fuel cutoff as others have stated.. Both the fan sensor plug (the single wire round plug) and the fuel shutoff (the double wire square ended plug) are in the same harness and should be clipped to the brake proportioning valve below the brake master cylinder hanging there awaiting a hook up.

thats it! the Casrb Cooling Fan ground! How important is it? Is it just needed when it is hot out? will it have anything with me not being able to rev the engine high?

thanks for the help!!!!!!!!
The carb cooling fan is supposed to turn on when the engine it turned off. It uses a timer as well as the temperature sensor shown above. It cools the carburetor so the residual heat from the engine doesn't evaporate all the fuel. It's operation has no effect on how high the engine will rev.
