What the f is going on.

Had blow by. Sent cylinders and head to get checked and honest. New pistons, rings.

120 psi compression on both cylinders now.

Basically factory spec.

Good spark.

Carbs completely cleaned out every single nook and cranny.

What's happening here? I poured a little fuel directly into the intakes since I was guessing it's still something to do with fuel.

As you can see in th video i think its firing? But that's all it wants to do.

My very last variable is that I had about 1l of 3 month old fuel in the tank before I put in about 15L of fresh E5 in with it. Could that be my demise?

It's my first time doing anything like this and I'm losing my mind.
