Sounds slightly too lean on the LSN for run in and possibly a slightly high idle screw.
When you go more than half throttle, does it suddenly cut out or does it start to bog down and eventually die? If it's a quick cut, it's too lean. If it bogs down over time and then stalls, it's rich. Your best bet is to watch the youtube videos to get an idea of the sound the engine should be making. Tuning a nitro car is all in the sound.
