Welcome to the forum. To fix some of the ills you stated - for the kickdown calbe, you either need to get the auto kickdown linkage adaptor from redline weber or pace engineering, or make one - the tranny will not shift right without it. There is a wire from the tranny that goes to a sensor on the intake manifold that controls the OD to work once the motor is warmed up. Either the sensor is bad, not there, or the wire is just hanging there. That wire can be grounded to the grounding terminals on the intake below the carb and then the OD will work all the time. If the truck was originally an auto, there would be a button on the shift lever to turn the OD on or off - that could also be missing, bad, or not hooked up. We do have manuals online for you to trace out the wiring for this. As for the bog on secondary opening - is it running the stock mechanical pump or electric? Did you change the fuel filter back at the tank? We also love pics - condition not important.
