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.

The car has always had a slight bog if I stomped it hard, Once Im sure all is good.
I plan to get some metering rod / jet kits and try to fine tune it some.


A friend of mine has spare hemi carbs.
Ive actually toyed with the idea to pick up a spare set and have them gone thru by someone with a little more knowledge than me

My car also has a bog anytime I slam the throttle open in first from a slow roll. I worked on it for about 6 months a couple years ago with the help of Dragonslayer and never could get it worked out completely. The only thing that seemed to greatly lessen it was to replace the accelerator pump shooter with I believe .035 units from memory, and put the linkage on the inside hole. But I only tried that on the back carb and I think to get rid of it completely I would need to do it on both carbs. I decided I could live with it with my style of driving and just put everything back stock. But I went through the carbs completely with George’s suggestions and checks of boosters, all part numbers, gaskets, jetting, cleaning economizer passages out to spec, etc and it just seemed that it’s tough to get enough fuel down the throats when all 8 bores are suddenly opened at lower engine speeds.
