carb adjustment

Well, try removing the lokar cable off the carb, the throttle cable and see if the carb opens all the way with the engine off, maybe the lokar is not adjusted correctly. Sounds to me like the lokar kickdown is the problem, alot of people have issues setting these up without guidance.

The lokar kickdowns work really nicely if they are set up correctly. For more info on how to set up the kickdown look at Bouchillon performances website, they sell a mopar kickdown that is similar to the lokar, open their installation instructions and you can then see how yours should work.

If you cant get the carb to open without a screwdriver something is wrong. I'd take the carb off and inspect it for problems. Could be alot of things.

Is your choke adjusted and working correctly ? If the choke linkage is inplace and not set up - the secondaries may not open either, primarily if the choke fast idle linkage is bound up it will screw up the secondaries.

It sounds to me like you need to start over, meaning pull the carb, inspect it. Make sure there is not something wrong with the manifold opening for the carb. If its okay then reinstall the carb, check for WOT, if okay, set up the throttle cable adjustment, then hook up the lokar kickdown. If the lokar cable is really frayed it may cause issues, it should move smoothly.
