32bantam:
What are the butterflies set to?   If they are too tight...when you snap the throttle closed they might be cutting off air for just long enough to stall. open them up a few thou and try it....you will have to readjust the barrel valve.

hotrod316:

 Just screw the stop a little bit , no need to mess with the BV,  Its alcohol! as long as it comes off of idle clean and sharp the BV is fine.
 Fuel volume reacts to "G" force.  1g will move the fuel to fill the void at a 45* angle at the tail. If you are not carrying enough volume the fuel will move away from the pickup, and is quite common with the chute hit.
  Racing is too expensive to have problems, really need to have somebody build you a tank that works correctly
