Drag strip launch problem

went your foot is on the floor there is no vacuum....so you have no vacuum advance

afb secondairies throttle blades are opened mechanically ...but there is an air door that does not allow air to flow thru the secondaires until engine rpms come up...the air door is not adjustable....can not see the car being out of gas less then one second after launch....

either the fuel is sloshing and killing the engine....or you launch rpm is not high enough for the engine too move the car....hence bogging...
