[DeTomaso] Holley Problem

[Will Kooiman]

Yep - I did that too.  It didn't help.

I seem to recall that it was the primary side that overflowed on braking,
though.  That's contrary to what I'd think, but that's how I remember it.

The stock Holley came with vent whistles - brand new about 3 years ago.  Who
knows when they started coming that way.

Will.

It would help if they reached close to the opposite wall and the fuel level
was low enough not to cover the tube openings at full braking. This requires
notched floats (which I think is available) to retain full float movement.

  I can remember attaching small tubes to the jets that reached to about the
center of the float bowl that I thought were suppose to address something
like this.  Would that help this condition?  

  There must be a lot of road racers who solved this kind of problem years
ago.

    It's the secondary bowl that overflows on braking. While a vent whistle
may improve your flooding problem there's little that can be done about the
flooding that occurs through the main circuit into the venturi jets.

    > It seems like my engine has always wanted to die when I step on the
brakes with the car in neutral while coming to a stop. The problem seems to
be worse with the new intake manifold that is tilted as opposed to the
previous level Blue Thunder. I tried Jack's suggestion of running a piece of
tubing from one vent to the other with a small vent hole drilled into the
high point of the line, no improvement. Float level is set below the sight
glass in the primary bowl. Float level is set at the sight glass at the
secondary bowl. After the engine dies, it blows a little black smoke when I
fire it up, so I figure it is flooding out. How is that happening? I don't
understand how gas is getting out of the bowl and into the intake manifold?
I guess I just keep lowering float levels until the problem is solved or
until the engine starves for fuel?
