Reply to "Fuel Starvation"

Kevin,

I also own the 670, and have exactly the same problem! Thought I was alone. My problem occurs at full throttle, starts around 5000 RPM, bogs for a moment,
then continues accelerating. I have written Holley...no reply. I have checked my float level on the secondaries, and all seems normal. Next, I will try a different vacuum spring for the secondaries. There is an extensive trouble shooting guide on the holley website. They suggest the secondary springs. Let me know if you fix it

Thanks, Tom
