yes i did a compression test. I forgot to mention in my previous comment.
Compression is between 70 and 110 psi. (cold)

I understand your reaction that I don't know 100% that the ignition is perfect. But if one block runs well and the other continues to experience exactly the same problems, you can still say that the problem is not with the ignition.
I have placed my ignition on the 40er pickup and it runs perfectly.

It is so strange that the engine idles perfectly and at full throttle. And if you accelerate slowly, it's okay. And when you give full throttle from idle, the engine chokes.

does anyone have any ideas what I can check?
