For Holley carbs
I had a stumble off idle it felt like my pump shot was lean and not getting enough gas off of idle. This was bigger than my factory pump squirter and gave me more fuel sooner coming off idle and completely eliminated the stumble I had.

Just what I needed
Worked great to help me fine tube my Brawler carburetor. Definitely out performs the Edelbrock that was on it.

Just what I needed
Not much to say here, if you are a tuner then you know what you are looking at and what it does. I have no complaints with these nozzles. The larger 35 size along with a accelerator pump cam change has eliminated my backfire.
