carter afb drains into intake overnight

[75k20]

I have a carter AFB carb and overnight the fuel bowl drains into the intake manifold. this makes the truck have really bad starting problems in the morning.

when I take off the air filter and look into the manifold I can see the fuel sitting in a puddle. i tried to pump the linkage multiple to see if i could get it filled up but could not see any fuel getting squirted out.

is there an adjustment I can make to the float on these carbs? usually, I just give the truck a little bit of starting fluid and once it starts off the fluid I can keep it alive until the bowl fills up again.

any help is appreciated.

I'd pull the carb off and see if there are any plugs on the bottom that might be leaking or a crack in the body of the carb.

Try taking the gas cap off when you get out next time and report any findings.
