carburetor is leaking from top gasket

[prodjay10]

I was trying to fix the throttle because it sticks. It'll idle at 1000 to 1200 and when I goose the pedal it drops to 600. So I greased up the linkages and it wasn't sticking as bad, but when I was on my way back home the truck died and it was leaking pretty bad from the top carburetor gasket.

When I was greasing the linkages, I noticed it was wet on and around the carburetor to suggest that this isn't the only time it has happened, maybe just not as bad.

1971 c10 with monojet carb.

Any help would be appreciated. Thanks
