I was trying to get the secondarys fine tuned and thought that this would do it as both carbs have a lot of similarities. One of the things that's different is the size of the diaphragm. The 4100 is larger so therefore more powerful. I tried the strongest spring but it was weaker than factory. I ended up just stretching the stock one out to make them open later. Nice selection for a Holley though.
