The only "butterfly" that closes with the choke cable is the one at the top of the choke horn. Not the ones on the throttle plate.

you know those round flappy things that close off the big holes in the top of the carb. yea the metal lever that makes those open and close is the choke lever.

there should be a rod that goes up to the choke plate and a bracket at the other end that kicks the choke open at WOT there should be a place on that bracket to attach the cable to. here is a pic of where it should attach just below the screwdriver you see the bracket that holds the cable, the cable actually attaches to the linkage right above it

here is a good site that will tell you everything you need to know about tuning a holley carb Carburetor Tuning the Scientific Way

im well aware of which flys are suppose to close...i cant figure out where to put the cable on the lever to make it function correctly

Cathedral bowl Holley's aren't the best for off road, the floats tend to bounce
The side mounted float bowls can be spring loaded to help out in this area.
A 650cfm dbl. pumper on a AMC 304 , should give you about the same mileage I get with my 401.

I guess I jump the gun on that one.
