Re: holley carb secondary spring
Not sure if the spring you have is stock or not , but Holley has a spring assortment that you can select from , weaker to stronger.
I think this carb is from the 1850 series, single inlet, banjo fitting and fuel balance tube to rear bowls. Not a hard job to change, some times you have to remove the entire diaphragm to do this or get to the last screw near the choke, if it has one.
Any local performance shops in your area?
