BB D6H2 Carbs leaking

[Alshere59]

So my car has been sitting a few years. I went to start it and both carbs BB D6H2 leak badly. I will be checking the floats to make sure they are not stuck/level etc. but is there anything else that would cause this I need to look at? It has not been started in a few years and I rebuilt the carbs a while back but just got around to putting them back on the car. It fired up after a couple of cranks but pored fuel out of the hole below the float.

I would check the float needle valve. It sounds like it is sticking.

You can use a plastic handled screwdriver to tap the top of the carb where the fuel line is connected. Sometimes that frees it up.

Or you can disconnect the fuel line at the carb inlet and spray some Gumout/carb cleaner into the carb inlet. That may do it, too.

If not, remove the top of the carb and remove the float and needle valve and clean them up.

When I got my 51 one of the issues I had was a leaky carb.  Among the issues I found were loose screws holding the carb together and a inlet needle who's rubber tip looked chewed up.   There were other issues as well, but none I could say contributed to it being a leaker.  One good rebuild later, with attention to detail, and it no longer leaks nor does the bowl go dry on me.

Thank you for those the offered advice. I checked floats level, condition etc. Not that. I poured gas in the float bowl and it just runs out underneath. So I assume I botched the rebuild. So tear them apart I guess and see if I can see what I messed up. Update found the problem. I guess I forgot to install the rivet plugs in the main vent. I noticed it as soon as I pulled the carbs.
