Default carburetor flooding

1985 accord. Had a bad float so put in a rebuild kit. Could never stop the carb from loading up with gas. Installed rebuilt carb and still have the same problem. Checked the fuel pressure and it's just below 2 psi.
Carb rebuilder said that anything between .5 and 3.5 psi should work. So, actually my son is doing the work, trying to get the car going for my grandson, I'm just mostly in the way. Looking for any ideas of where problem might be before we either shoot the dang car or have it towed to a shop.
Thanks
Roger

If carb is flooding due to bowl overfill, the possibilities I can see are needle valve or needle valve seat is damaged and won't seal, float is flooded and doesn't provide enough lift to seal the needle valve, or needle valve is improperly adjusted (usually some lever is bent to adjust lift).

good luck

Thanks guys, for taking the time to answer.
Yeah, the problem began with what we thought was a bad float. So we put in a rebuild kit which included new floats, needles and seats, etc. That didn't help so we tried the old needle and seat with no luck. At that point we bought a rebuilt carb from importcarbs. com. After installing the rebuilt carb we let the car idle for about 10 minutes and then drove it around the block. It sounded and ran great. The next morning we drove it about 8 blocks to a muffler shop, and then back home with no problem. Then, started to drive to the inspection station and about half a block from home it loaded the carb with gas and died.
When we found the carb full of gas I called the rebuilder and he said it sounded like too much fuel line pressure, ( anything over 3.5 psi would prevent the needle from seating, according to him) so we put a guage on it at the carb and checked it 3 different times over a 4 hour period with a reading of about 1.8 psi. My assumption was, that since the problem began prior to the initial kit installation and continued even with the new (rebuilt) carb that the problem may be external rather than the carb. I can exchange the carb but hate to if the problem might be elsewhere.
Apologize for the long post.
Thanks
Roger

It could be the choke is not opening as the engine warms. This will eventually kill engine w/ too rich mixture, and cause hard/no start. Make sure choke system is working correctly.

good luck

This may sound random, but try replacing the fuel filter and fuel line from the filter to the carb.

It is possible for small deposits to block the needle allowing the bowl to over fill and flood.

Every time you tear it down these deposits get freed and cleaned so the car runs again until a new one makes it way into the float bowl.
