Thermo quad float bowl adjustment

TQ brass floats, instruction that came with a kit stated 13/16. Also have issue with no idle mixture adjustment, any suggestions.
i disassembled the 9096 and attempted a good clean, tough idle at start, must feed the throttle, after warm up, engine holds firm 750rpm with 15 in vaccum, really good throttle response, but extremely rich and stinky exhaust.
vehicle is 1977 Dodge truck. W100 1/2 ton 4x4 Powerwagon
