Not sure what do to next

Hi there, Please watch video to end to see engine problem, on video I’m playing with choke to keep engine running, (needs carb cleaning), problem is that if I past half throttle sound like the engine is losing compression, almost at the end of the video sound like air is coming out from somewhere Thanks
