    One quick question my 71 v8 maverick starts rite up the 1st time I start it and throws no smoke at all. After driving it and I turn it off if I let it sit for about 20 minutes and try starting it, it takes bout 8 seconds of cranking before it starts and throws dark smoke. what can I do to fix this? What might the problem be?

    The choke is stuck shut on the carburetor.

    Dark smoke is raw fuel. You're flooding the carb trying to start it

    the gas may be boiling out of the carb and then the fumes go into the intake then cylinders. then it cools into a liquid and will "flood" the motor.
    when you turn off the motor you should be able to pop the hood and hear a boiling sound from the carb if this is the problem.

    Install a phenolic resin or wood spacer between carb and intake to stop heat transfer to carb.
    This solved the same problem on my 73

    Yep boiling the fuel. Also a high float level from a sticky needle valve will exagerate that problem. Thought mine was boiling since the symptoms were dead on and it was dribbling in fuel after shut off. Turns out it had a tiny piece of neoprene in the rear needle and seat.
    Either way it shouldnt be hard for you to figure it out and fix it.
