Someone can correct me if I'm wrong, but to my knowledge the valve seats in a 73 are designed for leaded gasoline and as such, a lead additive would be beneficial.
I can't understand what you're saying. What happens in between it running for a while, and you suddenly wanting to start it? Do you yourself shut it off and come back, or does it stall, forcing you to start it again? I assume what you're trying to say is that the engine has a hard time starting while at operating temperature. If that's the case, first make sure the choke is open while trying to start it at temperature.
This has nothing to do with ethanol blend fuel. Ethanol places a greater strain on some of the rubber components in the fuel system, but it catches a lot of undeserved blame. The issues you're having are going to happen with or without ethanol because something else is wrong. I think a lot of your claims against ethanol are unfounded. In particular, "clogs the motor" is a very ambiguous statement. Pipes can get clogged, but I don't know what a "clogged motor" would look like.
This is why, when seeking help for a problem, you need to state the problem, not what you believe to be a possible solution.

I seriously doubt that your issues are a result of ethanol. How did you prove or what was your source that indicated ethanol "clogs the motor"? Running a lead additive won't hurt anything but I really don't think it will fix your problem. But if you could link your source I would love to read it...

the only true statement he has made is that ethanol does absorb moisture quicker due to the alcohol content...by no means am i a ethanol for all kinda guy just dont see how it can clog an engine?? ethanol has a higher octane rating than reg gas hence one of the reasons the boys at nascar even use it now..like mentioned rubber seals and such dont like ethanol so much ..so a lead additive wont hurt ,but you probably have issues elsewhere...

I think what he may be may be getting at as far as clogging the motor is that ethanol acts as a detergent. These old fuel tanks can have all kinds of crud built up through the years. The ethanol can break loose stuff in the fuel tank which could clog fuel lines, filters, etc. Perhaps that is what he is referencing.

It sounds like there are other issues to be dealt with first...
Its an old truck and if it was going to the scrapper (saw the story in another thread) it probably needs some love. I would rebuild the carb and adjust it properly after you change the fluids and give it a tune up. It should run fine on ethanol unleaded blend. I felt the same way about ethanol when it first came out but I eventually got tired of trying to find regular gas and nothing bad has happened that I can blame on ethanol.
