66 dart /6 carter carb leaking problems

[marners80]

Hi guys, Im new here and have searched around on solutions to my problem with no luck so far. I m pretty sure this thing has has leaked out of the top of the accelerator pump piston to some extent the entire time I have had it(around ten years). I had it rebuilt maybe six years ago not because It was running badly but because of the leaking.
This was my first car and I have put around 60k on it and its always started and ran well. I drove it to work for several years but now its more of a weekend/summer car since its a convertible.
A couple months ago frustrated with the leaking I sent it to a specialty carb shop to have it rebuilt again because I assumed it would come back with out the leak........It still leaks at the same place it always has. Ive considered getting a reman holly but I really like the way the car runs with the carter. I have picked up several rebuild kits just to see if i was missing a part somewhere around pump top with no luck. I have double checked the float level several times and set according to rebuild instructions. Im out of ideas.

The picture is from before the last rebuild. there is a floating washer that sits on top of the hole. tonight I tried putting a small spring between the pump top and the linage hook just to put some down pressure on the washer....didnt really work. any ideas ive stupidly overlooked?? thanks

Judging by your photo, you don't have a float valve unless it was installed after this was taken! Still, if fuel is coming out the top, you have a float level problem. Either a bad float, out of adjustment, bad valve, dirt in the line, or a combination of those. Going to the 1 bbl. 1920 Holley is no improvement IMO.
