Leaking carb under throttle body spring.

I have a gas leak at the throttle body of my carb (84 cj7 258 stock carb). It's where plastic and metal meet just under the large spring that sets the adjustment screws. I can't find a way to pull them apart nor due I see any previous gasket. I cleaned out the inside of the carb and the two screws on the inside so they are not clogged. I was thinking over flow of gas might be getting to the this spot. Any help to fix this would be greatly appreciated.

Can you get a closer picture and point to where the leak is? Is it leaking between the carb base and intake manifold? Or from the carb body itself somewhere? If its behind that large spring on he right of the pic it could be a worm throttle shaft. Is it just damp or can you see fuel dripping? If its leaking where the carb joins the intake that gasket looks pretty pooched.

Yea the gasket will get replaced. It's a steady drip with the motor running. You can see in this pic the gap between the throttle body and the plastic piece the spring goes around. That's where he leak is. There is not an gasket or rubber ring that I can see and I can't find a screw that tightens the two together.

Sounds like the throttle shaft needs to be re-bushed then.

So you think a bushing goes between the body and plastic piece? Thanks for the help.

No. The throttle shaft passes through the plastic piece piece that the spring is wrapped around and them goes in one side of the carb body and out the other. Thinking the aluminum of the carb body where the shaft rides has worn and fuel is allowed to pass through the body along the throttle shaft and drips out between the plastic part and the body.
