    Pros:
    • Product description is spot on
    • Restores smooth idle
    • Correct OEM color
    Cons:
    Thanks for offering this spring. The original Holley 4560 carburetor was in a million pieces in a 5-gallon pail when I started my project. After it returned from a complete restoration, I mounted it on the intake, ran the engine and dialed in base settings. What I thought was the correct spring in the pail was from a 302 engine and wouldn't return the throttle to the correct base position. Your description in the product details was spot on. After ordering and installing this spring the idle returned smoothly to the proper base setting and I've had no problems since. Even the color is the correct OEM shade!

    Good stiffness

    Have tried many generic throttle springs. Too stiff or too soft. This one is just right. Not real hard to accellerate. Stong enough to pull back to a consistent idle speed.
