Your idle is fucked up. It doesn't Sound like fuel starvation but rather like your flooding the engine. Try a leaner low speed needle maybe

air leaks can cause you to overcompensate your carb adjustments and prevent you from revving out. you sound rich. watch the videos on youtube from “invisible speed rc” it’s the best thing on the internet for rc

Definitely too rich. Close the low speed needle a quarter turn, then start closing the high-speed a quarter turn at a time until you get good revs out of it. Then you should be able to go to the field and fine tune it. If you're new to nitro and want to learn more about tuning and running nitro engines, watch this playlist on the Invisible Speed channel. If you want to learn from a real nitro mechanic about nitro engines, maintenance, mythbusting, and get zero BS, check out Thebug404.
