VA FC Cranks, Sometimes Starts for a Bit, Smokes, then Dies

So it's done nothing but this for the past three hours. I've gone through de-flooding procedures multiple times. Once I had it run for maybe a minute but had to hold the key in the start position for it to stay running. It smokes like crazy then dies. I've been pulling the plugs repeatedly, cleaning them, drying them, disconnecting fuel pump then cranking until I don't see the mist coming out anymore, put the plugs back in, connected the fuel pump and it starts for maybe 10-30 seconds while smoking like crazy, then dies. The smoke is always constant.

Any ideas? I was wondering if its the MAF, but that wouldn't cause all the smoke that I know of.
Here's a video of one startup.

sounds like what mine was doing, but once mine started it could use the throttle to keep it running. I ended up with no compression. And it was all because of carbon build up.

Maybe I'll run a compression check and see. I've got some carb cleaner I can spray in there. Would tht help?

Compression or leak down test should shed more light on this, sounds like a seal isn't doing its job. I agree with the other posters.
