These springs work against vacuum to transition the rods from cruise to power. In cruise mode vacuum pulls the rods down against the springs and the carb runs relatively lean. When vacuum drops during acceleration the springs push the rods up into power mode. If the spring pressure vs. vacuum is off, the transition to power mode is too slow. Edelbrock sells a set of springs that are rated in 3" to 8" of vacuum. A higher rated spring transitions to power mode sooner, which can help part-throttle bog.
Its full throttle launches from a dead stop. If I get up on the converter and ease into it there is no problem.
