If the LSN is turned too far in I think if might cause that. It could be just running on the fuel you force in the carb if blowing it in. Someone correct me if I am wrong but maybe. Just turn out the LSN 1 or 1.5 turns just to see what happens. If it still does it try 2, if not that put it back to where it was so you do not lose your setting and try something else.
Sounds reasonable. I've had my buggy stall before when I gave it throttle simply because it was too lean.
