View Full Version : Quadrajet spring??

Buddy told me you can bend a spring on your quadrajet so secondary's start opening at 3/4 throttle versus 1/2 throttle. Any idea which spring?

Bending springs is a good way of making a carb never run properly
You can buy tuning kits that have different springs jets metering rods etc
By delaying when secondary open you could cause a lean condition and
Burn your motor if it runs good leave it alone quadra jets are finicky to modifications

There isn't a spring to bend, its the linkage from the primary throttle to the secondary. Adjusting this has no effect on the air fuel ratio.
