318 Won't Start? And I tested as much as I could I think?

The ICM is not field testable without special test equipment. Substitution is what is done. I'd try to find and OEM one off of eBay.. what you get from overseas these days is questionable.

The point of the teaspoon full of fuel down the throat is that the IF the ignition is good, then it will fire off with that, even cold. Since it did not fire off, then I am pretty suspicious that something is still amiss with the ignition. 1/4 cup? Wow, that is a TON; it shouldn't have taken that much.

Do you have a volt-ohmeter so other parameters in the ignition can be tested? Things like the actual ballast and coil resistance need to be checked to be sure you have the right parts. If so, and you are willing to run down some checks, then I can list some things to measure.

You mention fuel out of the jets; do you mean the small circular 'things' down inside the carb's throats? (Those are called auxiliary or booster venturi's... see the 1st illustration here:
Automotive Systems)

At idle, there should be NO fuel visible out of these at all. Your needle valve in the float bowl may be stuck open with dirt/crud and just flooding things.. or the float level may be way off for some reason. Doing the carb rebuild is on track to clear up things like that.

Sounds like you may be plagued with 2 problems at the same time...carb + ignition. It happens.... not to mention the ball joints on the DD!
