Yeah, that lever plate just moves the throttle cable to the other side of the carb. I'm not sure why it's included in the kit as it wasn't needed here. It would be needed for the reverse pull version though...

As far as the blue wire goes, I didn't use it. I just found a +12v line that went to the old carb and used it to hook to the choke. It was one of the red wires.
