note that eventhough C22 and our A12 shares the same 5 speed gearbox, the third gear ratio is different. C22 have closer ratio while out datsun have wider ratio. that is why 3rd gear is best for dragging.

for me... just increase until got knocking.. then retard 2 degrees... this is the best throttle responds. but harder to get top speed. Jee1's technique will get better FC and speed.
