Re: Double pumper Holley problem.....

It's obvious that you've missed something in cleaning it or it's an assembly problem. You can chase some passages with torch tip cleaning needles.

Are you only missing fuel from the accelerator pump nozzles, or are you not getting fuel from the boosters ? (or both)

At one point, the secondary boosters were dripping fuel, I learned that's a indication of too high of float level....lowered it and stopped dripping..this happened also with primaries...lowered level to stop dripage. So both as you asked.

I've got torch cleaning tips...and have ran through all passages....if I can spray carb cleaner clearly through passages how is there still blockage??
