Hi all,
I have a Holley 670 avenger. I think the car is running rich. I thought in adjusting the primary float , but it seem to be appropriately adjusted according to holley recommendations. I checked the secondary float and it was pouring gas whe I removed the side screw.I couldn’t find clear recommendations for secondary float according to Holley. Does any of you know the correct level of gas in the secondary float?
Thanks in advanced, and be safe!

 

Like almost any other Holley, just below the threads of the sight glass/plug.
Here is a link to Sofa's Holley tuning sticky: https://www.thirdgen.org/forums/carb...ey-tuning.html

 

The primary should be right up to the level of the plug, almost coming out on its own, and the secondary should take a considerable jog on the fender to make it dribble.

 

thank you so much!! it helps a lot.

 

One thing: Are these levels with the car off or on?

 

Running.

 

A follow up: so This morning, i recheck the primary bowl level and the secondary level Of fuel to double check before adjusting. I also Replace a new gasket on my Gas cap and disconnect and reconnect the tubing of egr solenoid for better routing. I proceded to Turn on the car and it Choked. Sound like the engine was stuck and not turning. After few attempts, finally came on, white smoke came out thru pipes, and it has rough idling. It doesn’t stay on unless i am on the gas. Is this temporary? Did i mess up something?any help is appreciated.
