changed my oil and it had fuel in it. Now I have just re did my manifold gaskets and checked for vacuum leaks. The card fast idle was adjusted as well. Now how do I make sure the primaries aren't open to much at idle. How do I set the secondaries to open a bit to help idle? I just hooked up a vacuum line to my choke so that should help. I did have a rich condition before and due to my mods and rejetting it may be taken care of but the smell of my exhaust tells me different.

If there was enough fuel in the oil that the oil level was above the full mark on the dipstick, you may have a ruptured diaphragm in your fuel pump.

Generally if you get a large sudden dose of fuel in the oil it's the fuel pump. If you've been doing a lot of coldstarts, or short run times it could be from the choke always being on.

I think it is due to the carb being overly rich. I'm working on narrowing down the cause. The transfer slots are good and the throttle blades on the secondaries are good. I opened then a but to help idle. The choke is doing something but what I'm not sure. It is set to pull off immediately so I adjusted the fast idle last night which was all the way out. I moved it about half way in and it did nothing for my motor. I find it hard to believe my jetting is off 72 in front and 74 in rear on a 406sb with a big cam. It does spit at random in idle if you goose it or if running on hwy and goose it so I wonder if my squiter should be a size bigger. I know before it was running to rich and the fuel washed my rings and that is how it got in the oil. I just can't find where the leak or fuel is coming from. I'm going to buy a book on holley tuning to help me out. I'm eating plugs alive and never had this issue until I changed my heads to afr which made me lean. In between rejetting it now has become to rich. I think I'll redo the gaskets since I have changed the jetts around allot.

A Holley can do this if the needle valve is damaged, if the float is stuck or has fallen off it's pivot rod (has happened to me 3 times).

To check the likelihood of this, simply check your float levels. The fuel level is supposed to just barely trickle out of the sight plugs on the sides of the bowls. If the levels are too high, this could be the source of many of the problems you've been discussing lately.

You could also have a blown power valve in your Holley which would cause many of the above problems, make it run rich and could contribute to the gas in the oil issue as well.

My fuel bowl levels are just below the top of the eye. So if you looking at it the circle is 3/4 full.

It may not be your only problem, but that's way too high.

Kevin,

I agree with Dyno Jonn. All the Holleys I have ever seen want the fuel level to just be at the bottom of the circle. In the days of solid plugs that you had to pull out, you wanted to have just the barest trickle of fuel with the site plug out. My new Avenger has the little plexi window, and it states that the fuel should be "barely visible" at the bottom of the window. This could be causing a lot of your carb problems.

I will not be happy if that is the issue. So simple. Let me doulble check that is where the fuel level is at.
