Review on Holley 20-13 Secondary Diaphragm Spring π§ Kit: Maximum Performance Upgrade for Reliable Engine Efficiency by Andy Metzger
Proper springs for Holley carburetors.
These springs are good for the job. I went my way from the lightest to the one that worked for my application and they seemed properly positioned and well constructed. The colors were easier to read than I thought.
Pros
- Good work
Cons
- I don't remember but there was something
