75 SCAMP DIES WHEN I STAB GAS PEDAL FROM PARK TO DRIVE. RUNS GOOD OTHER WISE

First things first:
[1 ] Remove carb & check float level, should be 7/16". If you are careful, you will not need any gaskets.
[2] Turn the carb over & see how much transfer slot is showing at idle. 0.020-0.040" is ideal, 0.060" is iffy & more is no good. This dimension is critical to carb operation.
[3] What is the ign timing at idle?
[4] Report back.
