1974 6HP Johnson Running Very Rich Wont Idle

[yelladog]

I recently rebuilt the carb on this motor and am having some problems. Runs good if opened up but will not idle. Pulled the plugs and are very, very wet. Can see small puddle of gas in carb at the front. Obviously I am running very rich, but cant seem to correct it. The only adjustment that I'm aware of, is the slow speed knob on the front. Thanks alot, Brian C.

There are a few things that can cause the problems you are getting.
Carb float, when you reassembled the carb did you check to make sure the float moved freely and that when turned upside down the float sat level with the carb body and that the float valve closed. A quick fix for a sticking float is to rap the side of the float bowl with the handle of a screwdriver, the jolt may free it up.
Main Jet seal, Did you replace the large rubber seal on the bottom of the main jet.
Needle valve adjustment, Screw the needle valve in until it seats lightly then back it out 1.5 turns
