I've been using My 1964 Chrysler New Yorker to drive to work a couple times a week this winter, it lives outside and was running and driving great last Monday, I let it sit for one day and come Wednesday it turns over but won't start, battery is new and I'm getting gas in the carb as it fires making an attempt to start but can't, I tried it again this Thursday and it was a repeat process, cranks and tries to start but can't, the only problem I can think of that could've caused this in such a short time is spark plug condensation, as I can't think of anything else that would cause an engine not to start after it had only been sitting for one day when the day before is started right up and was running great, but any other ideas are appreciated. The ignition system all been replaced with MSD ignition and MSD wiring, it's fairly new, though maybe condensation could be somewhere else?
A dirty air filter on a carburetored engine is like having the choke on all the time. Of course it will flood out. Examine your choke linkage and settings too.
I've seen condensation inside the distributor cap prevent an engine from starting. So can a large vacuum leak - that happened to a friend's car when his power brake booster suddenly developed a massive leak.
If you're getting fuel, the engine is OK internally, no big vacuum leaks, and ignition timing is set right that pretty much leaves the ignition.
What is spark plug condensation? Why do you think such a thing even exists? If the plugs are wet with anything, ie, coolant or fuel, you have other major problems.
Follow up to this: The fuel system is good and functioning properly, MSD 6AL system seems to be working fine at first glance, I'm going to check spark flow and check the spark plugs to see if they're fouled, turns out that if you flood a carbureted engine repeatedly especially during the winter it'll foul the spark plugs relatively quickly...and I have flooded this car quite a few times in the last few months, I did just last week at the gas station which was a few days before I couldn't start it, add the dirty air filter I was using to that and well...perhaps I should just check the spark plugs and see what they look like.
Update #2: plugs look fine, they have normal wear at least from what I can tell, I also did an ignition system test and got spark, so no problem there. However when I tried to get spark with the white wires and the coil plug I got nothing, and I tried different ways to test it to make sure I wasn't doing it wrong I still got nothing, so perhaps it's the coil? I've kinda narrowed everything else besides the possibility that the timing could've jumped.
