Holley float help

by Brent McNab » Tue, 02 Sep 2003 12:28:13

I have just installed a Holley Street Avenger 670 carb.  I tried to
adjust the float level in both bowls but got a little overzealous with
the rear bowl and screwed the nut in so far that it didn't contact the
needle and seat assembly.  I remove the nut and lockscrew and rotated the
needle and seat up far enough where the adjusting nut could contact it.

The problem is the adjustment doesn't seem to work.  I have the front
bowl adjusted fine, but the rear bowl completely covers the sight glass
with fuel.  I slowly turn the nut clockwise and the level will not lower.  
With the assembly being turned in as far as I did, is there a possibility
that the float height adjuster (however it may accomplish this) became
disconnected?  If so, I assume that I have to remove the bowl to fix it,
and what exactly do I do?

I'm assuming that is on the secondaries??
If so, Have you driven it and opened it up so that it would use some fuel?

What Bill is saying here is that it is damn near impossible
to adjust a Holley float from too high, down.  Fuel isn't
consumed anywhere near fast enough to see a meaningful
change in level.

Start with the float low and slowly work your way up to the
correct level.

Yes, this is the secondary (bowl closest to the firewall).  I have driven
it around, but it started raining and had to pull the car in because the
hood was off.  I'll try it again, thanks.

I see.  Thanks, I'll drive it around again and play with the float level.
