Try making the idle a bit richer and then starting it at night.

If I push the gas all the way down it will eventually start and also be revved to like 3k.

that note: "make it rev for a split second ... as soon as i stop cranking it" makes me believe Kmatch has nailed it.

try running a wire from the 'I' post of your starter selonoid directly to your coil+ and see if that resolves it (this will feed your coil 12V+ while you crank)

I live in California so it's not too cold or damp outside at night. My buddy thinks the engine just isn't broken in yet. I think the carb or distributor might be defective.
