You've got a clogged idle passageway somewhere. Try this before you dig into the carburetor- - - -Rev the engine up close to cruise RPM and slap your hand over the top of the carburetor. Hold the throttle wide open as the engine bogs down. Take your hand off, and let the flood clear out and rev the engine again. Repeat several times. Choking the carb down at high RPM floods all the passageways with liquid gasoline from the float bowl, and it might flush out the clog. If that doesn't help, dismantle the carb, soak it in a dip cleaner, flush with HOT water and use lots of high pressure air to blow all the passages clear. Reassemble with the correct rebuilding kit, making sure all the parts of the kit match up with what you removed.
