Leaking Fuel

[Targetking]

Holy ####.  Started my 1982 CB750K today and fuel started pouring out from the bottom of the carburetors (I think from the left side).  I mean, pouring out BIG TIME!  Since I don't like the idea of putting my face really close to a carburetor that's leaking gasoline onto a tailpipe that is starting to get hot (how do you say "fire!"), does anyone have any ideas off of the top of their head as to what could be wrong.  The engine runs fine, so I know that the carb's are getting fuel.  HELP! (and thank you!)

There are screws at the bottom of the bowls that, when opened, let gas out. Make sure all screws (one for each bowl x4 bowls) are tight.

^^^What he said. Also,verify that the float needles are not sticking. Pretty common if a bike has sat for some time with fuel left in the bowls. It gums up and...well,makes the floats/float needles stick.:)

O-rings on the fuel supply cross tubes?

Thanks for the advice.  Just got back in town after being gone for a couple of weeks.  Will take another look at it in the next day, or so.  Will advise.  Thanks again!!!

Tap the carb bodies with a screwdriver handle. May release sticking float valve.

For future reference, try using SeaFoam in the gas tank, once per month, when riding regularly, and use it per directions on the can, for storing the bike for more than two weeks.  SeaFoam will dry out the gasoline/absorb water, dissolve minor varnish deposits within the fuel system, and it will preserve gasoline (including ethanol blends) for up to 12 months -- don't let it go longer than that, or it will turn to green varnishy, sludge.

By using it once per month, you will prevent most carburetor issues, by keeping the system squeaky clean.  Also, remember to keep the gas tank topped off as much as possible, when storing.  Air space within the tank allows for water condensation to occur, which can lead to rusting, as well as fuel issues.  Cheers!
