600 Eddy tuning

The springs are for part thottle accereration, when the pedal goes half way to the floor kind of thing.
Metering rods are for the mixture. If the car is running rich, change them to thicker ones.
A bog is a off the line issue concerning weak acceleration. To much pumpshot is a reason. If goin to the hole fatherest away from the carb doesn't help much or at all, a small pumpsot cluster should be used.
If you move the pumpshot arm closer to the carb, what happens or is it in the closest hole to the carb allready?
