Fun day at the track but...need help with savage problem

Hi all! I was at the track today and things were going ok except for one thing. When I would come to stop the engine sounded erratic. Dedede dedededede dedede up and down. I can't figure out why it's happening. Also, when I fully apply brake it stalls. I'm running rich. I thought. Please tell me what you think.

Thanks, Dave.

Sounds like hot/lean idle to me. What's the engine temp?
