If it's leaking out an overflow line, the needle valve may be bad or stuck open, or the float level settings are wrong. All of those will let the carb overflow.

Who overhauled the jammed valve? Are you sure they got the cam and cam sprocket back on and timed properly?

itz not from d overflow line. i dunno how to describe coz i dunno where exactly itz leaking from. itz like my whole carb is wet til it drips.

a reconized local mech did the overhaul. anw, before he overhauled my top block, my carb seems to have a little leak. only today i found out itz worst.

2ndly, whats with my bike bogging? carb related too?

I'd check the simple things first. Make sure the fuel line coming from the tank to the carb is in good shape, not cracked and leaking. Take the carb out and make sure the float bowl oring is there and in good shape. While you have the bowl off, check/set the float levels. Check the tip of the needle valve for wear. Use compressed air or blow thru a straw and blow out all the little fuel passages of the carb.

What year and model bike is this?

It's the float valve...Fuel is continuing to flow into the bowl while it sits, and then when the bike is running it burns some of it down, so it no longer leaks, but bogs instead. It is an easy fix. Just bend the tab on the float, until it turns off at the right spot. I'm not sure what the spec is...
