The 23 T has a strange problem.

Prior to taking the car apart and rebuilding it, the fairly new Holley 600 single feed with vacuum secondaries would leave a puddle of fuel on the intake.

After rebuilding the engine, blowing out the carb, and putting it back on...it started doing it again.

Then, while running, the carb started flooding on the secondaries off and on.

I pulled it off and slapped the 600 from my 69 Camaro on. I did not note any leaking on the intake over night, but it started flooding on the primary side off and on while running.

I rebuilt the 600 using all new gaskets, needle, seat, etc.

Set it all back up and had great success for a day or two. Then, it started leaking out again.

Yesterday we tried running it around the block. Every couple of minutes the primary venturies would just start dripping and flooding. I could clear it out by hitting the accelerator and holding it down for a bit.

I have a new fuel filter, and it is a standard stock style mechanical fuel pump. I have new fuel line to to the tank.

Now...on the T, the gas tank is higher than the carb, or as high as the carb. Does this create a problem?


What gives?

I talked to the Holley tech line and did not get any real solid advice, other than to try the rebuild...which I did.

Considering it has done this on both carbs, and a new set of float needles...??????

Thoughts?
