1966 hemi carbs flooding

[gtx6970]

Are you sure that it’s not leaking through the throttle shafts? I think that I had heard somewhere that when they wear they could leak but I would think that they would leak air in and not fuel out. Also they would leak when the engine was running as the air/fuel was flowing past the shafts. While you have the carb off the car hook an electric fuel pump to it and confirm were the leak is. If it doesn’t leak it has to be the shafts I would think.

It had fuel running down the side of the carb body , So Im 99% sure it had either a binding float or stuck open needle/seat


Its back together and running. Drove it to a local cruise near me Saturday .
Plus had it running a while in the driveway yesterday for about half hour to monitor fuel pressure
No leaks - flooding = so far so good

Mine have loose primary throttle shafts but the only fuel that leaks out of them is when I prime the engine down the throat, or spill a little gas down the throat when filling the bowls. But it is a vacuum leak when the engine is running and I plan to have them bushed sometime.

Sounds like you did a good rundown and caught it along the way. I’ve had junk get in and hold the floats open, never to the degree of running over the carb though.

On shafts, when they get real bad it causes and hanging idle as they get the blades caught in the bores.
